--gui-lang llcode By default, the GUI tries to deduce your language from the environment (on Windows via the registry, on Unix via "LC_MESSAGES"). If that fails you can select a different language by giving this option with a language code (based on ISO 639-1).  Currently supported (but not necessarily completely translated) are: English (en, default), Czech (cs), German (de), French (fr), Italian (it), Japanese (ja), Dutch (nl), Polish (pl), Brazilian Portuguese (pt_BR), Russian (ru), Slovak (sk), Slovenian (sl), Serbian (sr), Ukrainian (uk), Vietnamese (vi), simplified Chinese (zh_CN), and traditional Chinese (zh_TW).
--debug-translation In GUI mode, this switch tells "tlmgr" to report any untranslated (or missing) messages to standard error.  This can help translators to see what remains to be done.
--machine-readable Instead of the normal output intended for human consumption, write (to standard output) a fixed format more suitable for machine parsing.  See the "MACHINE-READABLE OUTPUT" section below.
--no-execute-actions Suppress the execution of the execute actions as defined in the tlpsrc files.  Documented only for completeness, as this is only useful in debugging.
--package-logfile file "tlmgr" logs all package actions (install, remove, update, failed updates, failed restores) to a separate log file, by default "TEXMFSYSVAR/web2c/tlmgr.log".  This option allows you to specify a different file for the log.
--pause This option makes "tlmgr" wait for user input before exiting.  Useful on Windows to avoid disappearing command windows.
--persistent-downloads --no-persistent-downloads For network-based installations, this option (on by default) makes "tlmgr" try to set up a persistent connection (using the "LWP" Perl module).  The idea is to open and reuse only one connection per session between your computer and the server, instead of initiating a new download for each package.
If this is not possible, "tlmgr" will fall back to using "wget".  To disable these persistent connections, use "--no-persistent-downloads".
--pin-file Change the pinning file location from "TEXMFLOCAL/tlpkg/pinning.txt" (see "Pinning" below).  Documented only for completeness, as this is only useful in debugging.
--usermode Activates user mode for this run of "tlmgr"; see "USER MODE" below.
--usertree dir Uses dir for the tree in user mode; see "USER MODE" below.
--verify-repo=[none|main|all] Defines the level of verification done: If "none" is specified, no verification whatsoever is done. If "main" is given and a working GnuPG ("gpg") binary is available, all repositories are checked, but only the main repository is required to be signed. If "all" is given, then all repositories need to be signed.  See "CRYPTOGRAPHIC VERIFICATION" below for details.
The standard options for TeX Live programs are also accepted: "--help/-h/-?", "--version", "-q" (no informational messages), "-v" (debugging messages, can be repeated).  For the details about these, see the "TeXLive::TLUtils" documentation.
The "--version" option shows version information about the TeX Live release and about the "tlmgr" script itself.  If "-v" is also given, revision number for the loaded TeX Live Perl modules are shown, too.
help Display this help information and exit (same as "--help", and on the web at <https://tug.org/texlive/doc/tlmgr.html>).  Sometimes the "perldoc" and/or "PAGER" programs on the system have problems, resulting in control characters being literally output.  This can't always be detected, but you can set the "NOPERLDOC" environment variable and "perldoc" will not be used.
version Gives version information (same as "--version").
If "-v" has been given the revisions of the used modules are reported, too.
backup backup [option...] --all backup [option...] pkg... If the "--clean" option is not specified, this action makes a backup of the given packages, or all packages given "--all". These backups are saved to the value of the "--backupdir" option, if that is an existing and writable directory. If "--backupdir" is not given, the "backupdir" option setting in the TLPDB is used, if present.  If both are missing, no backups are made.
If the "--clean" option is specified, backups are pruned (removed) instead of saved. The optional integer value N may be specified to set the number of backups that will be retained when cleaning. If "N" is not given, the value of the "autobackup" option is used. If both are missing, an error is issued. For more details of backup pruning, see the "option" action.
--backupdir directory Overrides the "backupdir" option setting in the TLPDB.  The directory argument is required and must specify an existing, writable directory where backups are to be placed.
--all If "--clean" is not specified, make a backup of all packages in the TeX Live installation; this will take quite a lot of space and time.  If "--clean" is specified, all packages are pruned.
--clean[=N] Instead of making backups, prune the backup directory of old backups, as explained above. The optional integer argument N overrides the "autobackup" option set in the TLPDB.  You must use "--all" or a list of packages together with this option, as desired.
--dry-run Nothing is actually backed up or removed; instead, the actions to be performed are written to the terminal.
candidates pkg Shows the available candidate repositories for package pkg.  See "MULTIPLE REPOSITORIES" below.
check [option...] [files|depends|executes|runfiles|all] Executes one (or all) check(s) on the consistency of the installation.
files Checks that all files listed in the local TLPDB ("texlive.tlpdb") are actually present, and lists those missing.
depends Lists those packages which occur as dependencies in an installed collection, but are themselves not installed, and those packages which are not contained in any collection.
If you call "tlmgr check collections" this test will be carried out instead since former versions for "tlmgr" called it that way.
executes Check that the files referred to by "execute" directives in the TeX Live Database are present.
runfiles List those filenames that are occurring more than one time in the runfiles sections.
--use-svn Use the output of "svn status" instead of listing the files; for checking the TL development repository.
conf conf [texmf|tlmgr|updmap [--conffile file] [--delete] [key [value]]] conf auxtrees [--conffile file] [show|add|remove] [value] With only "conf", show general configuration information for TeX Live, including active configuration files, path settings, and more. This is like running "texconfig conf", but works on all supported platforms.
With one of "conf texmf", "conf tlmgr", or "conf updmap", shows all key/value pairs (i.e., all settings) as saved in "ROOT/texmf.cnf", the user-specific "tlmgr" configuration file (see below), or the first found (via "kpsewhich") "updmap.cfg" file, respectively.
If key is given in addition, shows the value of only that key in the respective file.  If option --delete is also given, the value in the given configuration file is entirely removed (not just commented out).
If value is given in addition, key is set to value in the respective file.  No error checking is done!
The "PATH" value shown by "conf" is as used by "tlmgr".  The directory in which the "tlmgr" executable is found is automatically prepended to the PATH value inherited from the environment.
Here is a practical example of changing configuration values. If the execution of (some or all) system commands via "\write18" was left enabled during installation, you can disable it afterwards:
tlmgr conf texmf shell_escape 0
The subcommand "auxtrees" allows adding and removing arbitrary additional texmf trees, completely under user control.  "auxtrees show" shows the list of additional trees, "auxtrees add" tree adds a tree to the list, and "auxtrees remove" tree removes a tree from the list (if present). The trees should not contain an "ls-R" file (or files will not be found if the "ls-R" becomes stale). This works by manipulating the Kpathsea variable "TEXMFAUXTREES", in (by default) "ROOT/texmf.cnf".  Example:
tlmgr conf auxtrees add /quick/test/tree tlmgr conf auxtrees remove /quick/test/tree
In all cases the configuration file can be explicitly specified via the option "--conffile" file, e.g., if you don't want to change the system-wide configuration.
Warning: The general facility for changing configuration values is here, but tinkering with settings in this way is strongly discouraged.  Again, no error checking on either keys or values is done, so any sort of breakage is possible.
dump-tlpdb [option...] [--json] Dump complete local or remote TLPDB to standard output, as-is.  The output is analogous to the "--machine-readable" output; see "MACHINE- READABLE OUTPUT" section.
--local Dump the local TLPDB.
--remote Dump the remote TLPDB.
--json Instead of dumping the actual content, the database is dumped as JSON. For the format of JSON output see "tlpkg/doc/JSON-formats.txt", format definition "TLPDB".
Exactly one of "--local" and "--remote" must be given.
In either case, the first line of the output specifies the repository location, in this format:
"location-url" "\t" location
where "location-url" is the literal field name, followed by a tab, and location is the file or url to the repository.
Line endings may be either LF or CRLF depending on the current platform.
generate generate [option...] language generate [option...] language.dat generate [option...] language.def generate [option...] language.dat.lua
The "generate" action overwrites any manual changes made in the respective files: it recreates them from scratch based on the information of the installed packages, plus local adaptions.  The TeX Live installer and "tlmgr" routinely call "generate" for all of these files.
For managing your own fonts, please read the "updmap --help" information and/or <https://tug.org/fonts/fontinstall.html>.
For managing your own formats, please read the "fmtutil --help" information.
In more detail: "generate" remakes any of the configuration files "language.dat", "language.def", and "language.dat.lua" from the information present in the local TLPDB, plus locally-maintained files.
The locally-maintained files are "language-local.dat", "language-local.def", or "language-local.dat.lua", searched for in "TEXMFLOCAL" in the respective directories.  If local additions are present, the final file is made by starting with the main file, omitting any entries that the local file specifies to be disabled, and finally appending the local file.
(Historical note: The formerly supported "updmap-local.cfg" and "fmtutil-local.cnf" are no longer read, since "updmap" and "fmtutil" now reads and supports multiple configuration files.  Thus, local additions can and should be put into an "updmap.cfg" of "fmtutil.cnf" file in "TEXMFLOCAL".  The "generate updmap" and "generate fmtutil" actions no longer exist.)
Local files specify entries to be disabled with a comment line, namely one of these:
%!NAME --!NAME
where "language.dat" and "language.def" use "%", and "language.dat.lua" use "--".  In all cases, the name is the respective format name or hyphenation pattern identifier.  Examples:
%!german --!usenglishmax
(Of course, you're not likely to actually want to disable those particular items.  They're just examples.)
After such a disabling line, the local file can include another entry for the same item, if a different definition is desired.  In general, except for the special disabling lines, the local files follow the same syntax as the master files.
The form "generate language" recreates all three files "language.dat", "language.def", and "language.dat.lua", while the forms with an extension recreates only that given language file.
--dest output_file specifies the output file (defaults to the respective location in "TEXMFSYSVAR").  If "--dest" is given to "generate language", it serves as a basename onto which ".dat" will be appended for the name of the "language.dat" output file, ".def" will be appended to the value for the name of the "language.def" output file, and ".dat.lua" to the name of the "language.dat.lua" file.  (This is just to avoid overwriting; if you want a specific name for each output file, we recommend invoking "tlmgr" twice.)
--localcfg local_conf_file specifies the (optional) local additions (defaults to the respective location in "TEXMFLOCAL").
--rebuild-sys tells "tlmgr" to run necessary programs after config files have been regenerated. These are: "fmtutil-sys --all" after "generate fmtutil", "fmtutil-sys --byhyphen .../language.dat" after "generate language.dat", and "fmtutil-sys --byhyphen .../language.def" after "generate language.def".
These subsequent calls cause the newly-generated files to actually take effect.  This is not done by default since those calls are lengthy processes and one might want to made several related changes in succession before invoking these programs.
The respective locations are as follows:
tex/generic/config/language.dat (and language-local.dat) tex/generic/config/language.def (and language-local.def) tex/generic/config/language.dat.lua (and language-local.dat.lua)
gui Start the graphical user interface. See GUI below.
info info [option...] pkg... info [option...] collections info [option...] schemes With no argument, lists all packages available at the package repository, prefixing those already installed with "i".
With the single word "collections" or "schemes" as the argument, lists the request type instead of all packages.
With any other arguments, display information about pkg: the name, category, short and long description, sizes, installation status, and TeX Live revision number.  If pkg is not locally installed, searches in the remote installation source.
For normal packages (not collections or schemes), the sizes of the four groups of files (run/src/doc/bin files) are shown separately. For collections, the cumulative size is shown, including all directly-dependent packages (but not dependent collections). For schemes, the cumulative size is also shown, including all directly- dependent collections and packages.
If pkg is not found locally or remotely, the search action is used and lists matching packages and files.
It also displays information taken from the TeX Catalogue, namely the package version, date, and license.  Consider these, especially the package version, as approximations only, due to timing skew of the updates of the different pieces.  By contrast, the "revision" value comes directly from TL and is reliable.
The former actions "show" and "list" are merged into this action, but are still supported for backward compatibility.
--list If the option "--list" is given with a package, the list of contained files is also shown, including those for platform- specific dependencies.  When given with schemes and collections, "--list" outputs their dependencies in a similar way.
--only-installed If this option is given, the installation source will not be used; only locally installed packages, collections, or schemes are listed.
--only-remote Only list packages from the remote repository. Useful when checking what is available in a remote repository using "tlmgr --repo ... --only-remote info". Note that "--only-installed" and "--only-remote" cannot both be specified.
--data "item1,item2,..." If the option "--data" is given, its argument must be a comma separated list of field names from: "name", "category", "localrev", "remoterev", "shortdesc", "longdesc", "installed", "size", "relocatable", "depends", "cat-version", "cat-date", or "cat-license". In this case the requested packages' information is listed in CSV format one package per line, and the column information is given by the "itemN". The "depends" column contains the name of all dependencies separated by ":".
--json In case "--json" is specified, the output is a JSON encoded array where each array element is the JSON representation of a single "TLPOBJ" but with additional information. For details see "tlpkg/doc/JSON-formats.txt", format definition: "TLPOBJINFO". If both "--json" and "--data" are given, "--json" takes precedence.
init-usertree Sets up a texmf tree for so-called user mode management, either the default user tree ("TEXMFHOME"), or one specified on the command line with "--usertree".  See "USER MODE" below.
install [option...] pkg... Install each pkg given on the command line, if it is not already installed.  (It does not touch existing packages; see the "update" action for how to get the latest version of a package.)
By default this also installs all packages on which the given pkgs are dependent.  Options:
--dry-run Nothing is actually installed; instead, the actions to be performed are written to the terminal.
--file Instead of fetching a package from the installation repository, use the package files given on the command line.  These files must be standard TeX Live package files (with contained tlpobj file).
--force If updates to "tlmgr" itself (or other parts of the basic infrastructure) are present, "tlmgr" will bail out and not perform the installation unless this option is given.  Not recommended.
--no-depends Do not install dependencies.  (By default, installing a package ensures that all dependencies of this package are fulfilled.)
--no-depends-at-all Normally, when you install a package which ships binary files the respective binary package will also be installed.  That is, for a package "foo", the package "foo.i386-linux" will also be installed on an "i386-linux" system.  This option suppresses this behavior, and also implies "--no-depends".  Don't use it unless you are sure of what you are doing.
--reinstall Reinstall a package (including dependencies for collections) even if it already seems to be installed (i.e, is present in the TLPDB). This is useful to recover from accidental removal of files in the hierarchy.
When re-installing, only dependencies on normal packages are followed (i.e., not those of category Scheme or Collection).
--with-doc --with-src While not recommended, the "install-tl" program provides an option to omit installation of all documentation and/or source files.  (By default, everything is installed.)  After such an installation, you may find that you want the documentation or source files for a given package after all.  You can get them by using these options in conjunction with "--reinstall", as in (using the "fontspec" package as the example):
tlmgr install --reinstall --with-doc --with-src fontspec
key key list key add file key remove keyid The action "key" allows listing, adding and removing additional GPG keys to the set of trusted keys, that is, those that are used to verify the TeX Live databases.
With the "list" argument, "key" lists all keys.
The "add" argument requires another argument, either a filename or "-" for stdin, from which the key is added. The key is added to the local keyring "GNUPGHOME/repository-keys.gpg", which is normally "tlpkg/gpg/repository-keys.gpg".
The "remove" argument requires a key id and removes the requested id from the local keyring.
list Synonym for "info".
option option [--json] [show] option [--json] showall option key [value]
The first form, "show", shows the global TeX Live settings currently saved in the TLPDB with a short description and the "key" used for changing it in parentheses.
The second form, "showall", is similar, but also shows options which can be defined but are not currently set to any value.
Both "show..." forms take an option "--json", which dumps the option information in JSON format.  In this case, both forms dump the same data. For the format of the JSON output see "tlpkg/doc/JSON-formats.txt", format definition "TLOPTION".
In the third form, with key, if value is not given, the setting for key is displayed.  If value is present, key is set to value.
Possible values for key are (run "tlmgr option showall" for the definitive list):
repository (default package repository), formats    (create formats at installation time), postcode   (run postinst code blobs) docfiles   (install documentation files), srcfiles   (install source files), backupdir  (default directory for backups), autobackup (number of backups to keep). sys_bin    (directory to which executables are linked by the path action) sys_man    (directory to which man pages are linked by the path action) sys_info   (directory to which Info files are linked by the path action) desktop_integration (Windows-only: create Start menu shortcuts) fileassocs (Windows-only: change file associations) multiuser  (Windows-only: install for all users)
One common use of "option" is to permanently change the installation to get further updates from the Internet, after originally installing from DVD.  To do this, you can run
tlmgr option repository http://mirror.ctan.org/systems/texlive/tlnet
The "install-tl" documentation has more information about the possible values for "repository".  (For backward compatibility, "location" can be used as a synonym for "repository".)
If "formats" is set (this is the default), then formats are regenerated when either the engine or the format files have changed.  Disable this only when you know how and want to regenerate formats yourself.
The "postcode" option controls execution of per-package postinstallation action code.  It is set by default, and again disabling is not likely to be of interest except to developers doing debugging.
The "docfiles" and "srcfiles" options control the installation of their respective file groups (documentation, sources; grouping is approximate) per package. By default both are enabled (1).  Either or both can be disabled (set to 0) if disk space is limited or for minimal testing installations, etc.  When disabled, the respective files are not downloaded at all.
The options "autobackup" and "backupdir" determine the defaults for the actions "update", "backup" and "restore".  These three actions need a directory in which to read or write the backups.  If "--backupdir" is not specified on the command line, the "backupdir" option value is used (if set).
The "autobackup" option (de)activates automatic generation of backups. Its value is an integer.  If the "autobackup" value is "-1", no backups are removed.  If "autobackup" is 0 or more, it specifies the number of backups to keep.  Thus, backups are disabled if the value is 0.  In the "--clean" mode of the "backup" action this option also specifies the number to be kept.  The default value is 1, so that backups are made, but only one backup is kept.
To setup "autobackup" to "-1" on the command line, use:
tlmgr option -- autobackup -1
The "--" avoids having the "-1" treated as an option.  (The "--" stops parsing for options at the point where it appears; this is a general feature across most Unix programs.)
The "sys_bin", "sys_man", and "sys_info" options are used on Unix systems to control the generation of links for executables, Info files and man pages. See the "path" action for details.
The last three options affect behavior on Windows installations.  If "desktop_integration" is set, then some packages will install items in a sub-folder of the Start menu for "tlmgr gui", documentation, etc.  If "fileassocs" is set, Windows file associations are made (see also the "postaction" action).  Finally, if "multiuser" is set, then adaptions to the registry and the menus are done for all users on the system instead of only the current user.  All three options are on by default.
paper paper [a4|letter] [xdvi|pdftex|dvips|dvipdfmx|context|psutils] paper [papersize|--list] paper --json
With no arguments ("tlmgr paper"), shows the default paper size setting for all known programs.
With one argument (e.g., "tlmgr paper a4"), sets the default for all known programs to that paper size.
With a program given as the first argument and no paper size specified (e.g., "tlmgr dvips paper"), shows the default paper size for that program.
With a program given as the first argument and a paper size as the last argument (e.g., "tlmgr dvips paper a4"), set the default for that program to that paper size.
With a program given as the first argument and "--list" given as the last argument (e.g., "tlmgr dvips paper --list"), shows all valid paper sizes for that program.  The first size shown is the default.
If "--json" is specified without other options, the paper setup is dumped in JSON format. For the format of JSON output see "tlpkg/doc/JSON-formats.txt", format definition "TLPAPER".
Incidentally, this syntax of having a specific program name before the "paper" keyword is unusual.  It is inherited from the longstanding "texconfig" script, which supports other configuration settings for some programs, notably "dvips".  "tlmgr" does not support those extra settings.
path path [--w32mode=user|admin] add path [--w32mode=user|admin] remove On Unix, merely adds or removes symlinks for binaries, man pages, and info pages in the system directories specified by the respective options (see the "option" description above).  Does not change any initialization files, either system or personal.
On Windows, the registry part where the binary directory is added or removed is determined in the following way:
If the user has admin rights, and the option "--w32mode" is not given, the setting w32_multi_user determines the location (i.e., if it is on then the system path, otherwise the user path is changed).
If the user has admin rights, and the option "--w32mode" is given, this option determines the path to be adjusted.
If the user does not have admin rights, and the option "--w32mode" is not given, and the setting w32_multi_user is off, the user path is changed, while if the setting w32_multi_user is on, a warning is issued that the caller does not have enough privileges.
If the user does not have admin rights, and the option "--w32mode" is given, it must be "user" and the user path will be adjusted. If a user without admin rights uses the option "--w32mode admin" a warning is issued that the caller does not have enough privileges.
pinning The "pinning" action manages the pinning file, see "Pinning" below.
"pinning show" Shows the current pinning data.
"pinning add" repo pkgglob... Pins the packages matching the pkgglob(s) to the repository repo.
"pinning remove" repo pkgglob... Any packages recorded in the pinning file matching the <pkgglob>s for the given repository repo are removed.
"pinning remove repo --all" Remove all pinning data for repository repo.
platform platform list|add|remove platform... platform set platform platform set auto "platform list" lists the TeX Live names of all the platforms (a.k.a. architectures), ("i386-linux", ...) available at the package repository.
"platform add" platform... adds the executables for each given platform platform to the installation from the repository.
"platform remove" platform... removes the executables for each given platform platform from the installation, but keeps the currently running platform in any case.
"platform set" platform switches TeX Live to always use the given platform instead of auto detection.
"platform set auto" switches TeX Live to auto detection mode for platform.
Platform detection is needed to select the proper "xz" and "wget" binaries that are shipped with TeX Live.
"arch" is a synonym for "platform".
postaction postaction [option...] install [shortcut|fileassoc|script] [pkg...] postaction [option...] remove [shortcut|fileassoc|script] [pkg...] Carry out the postaction "shortcut", "fileassoc", or "script" given as the second required argument in install or remove mode (which is the first required argument), for either the packages given on the command line, or for all if "--all" is given.
--w32mode=[user|admin] If the option "--w32mode" is given the value "user", all actions will only be carried out in the user-accessible parts of the registry/filesystem, while the value "admin" selects the system- wide parts of the registry for the file associations.  If you do not have enough permissions, using "--w32mode=admin" will not succeed.
--fileassocmode=[1|2] "--fileassocmode" specifies the action for file associations.  If it is set to 1 (the default), only new associations are added; if it is set to 2, all associations are set to the TeX Live programs.  (See also "option fileassocs".)
--all Carry out the postactions for all packages
print-platform Print the TeX Live identifier for the detected platform (hardware/operating system) combination to standard output, and exit. "--print-arch" is a synonym.
print-platform-info Print the TeX Live platform identifier, TL platform long name, and original output from guess.
remove [option...] pkg... Remove each pkg specified.  Removing a collection removes all package dependencies (unless "--no-depends" is specified), but not any collection dependencies of that collection.  However, when removing a package, dependencies are never removed.  Options:
--all Uninstalls all of TeX Live, asking for confirmation unless "--force" is also specified.
--backup --backupdir directory These options behave just as with the update action (q.v.), except they apply to making backups of packages before they are removed. The default is to make such a backup, that is, to save a copy of packages before removal.
The "restore" action explains how to restore from a backup.
--no-depends Do not remove dependent packages.
--no-depends-at-all See above under install (and beware).
--force By default, removal of a package or collection that is a dependency of another collection or scheme is not allowed.  With this option, the package will be removed unconditionally.  Use with care.
A package that has been removed using the "--force" option because it is still listed in an installed collection or scheme will not be updated, and will be mentioned as "forcibly removed" in the output of "tlmgr update --list".
--dry-run Nothing is actually removed; instead, the actions to be performed are written to the terminal.
repository repository list repository list path|tag repository add path [tag] repository remove path|tag repository set path[#tag] [path[#tag] ...] This action manages the list of repositories.  See MULTIPLE REPOSITORIES below for detailed explanations.
The first form ("list") lists all configured repositories and the respective tags if set. If a path, url, or tag is given after the "list" keyword, it is interpreted as source from where to initialize a TeX Live Database and lists the contained packages.  This can also be an up-to-now not used repository, both locally and remote. If one pass in addition "--with-platforms", for each package the available platforms (if any) are listed, too.
The third form ("add") adds a repository (optionally attaching a tag) to the list of repositories.  The forth form ("remove") removes a repository, either by full path/url, or by tag.  The last form ("set") sets the list of repositories to the items given on the command line, not keeping previous settings
In all cases, one of the repositories must be tagged as "main"; otherwise, all operations will fail!
restore restore [option...] pkg [rev] restore [option...] --all Restore a package from a previously-made backup.
If "--all" is given, try to restore the latest revision of all package backups found in the backup directory.
Otherwise, if neither pkg nor rev are given, list the available backup revisions for all packages.  With pkg given but no rev, list all available backup revisions of pkg.
When listing available packages, "tlmgr" shows the revision, and in parenthesis the creation time if available (in format yyyy-mm-dd hh:mm).
If (and only if) both pkg and a valid revision number rev are specified, try to restore the package from the specified backup.
--all Try to restore the latest revision of all package backups found in the backup directory. Additional non-option arguments (like pkg) are not allowed.
--backupdir directory Specify the directory where the backups are to be found. If not given it will be taken from the configuration setting in the TLPDB.
--dry-run Nothing is actually restored; instead, the actions to be performed are written to the terminal.
--force Don't ask questions.
--json When listing backups, the option "--json" turn on JSON output. The format is an array of JSON objects ("name", "rev", "date"). For details see "tlpkg/doc/JSON-formats.txt", format definition: "TLBACKUPS".  If both "--json" and "--data" are given, "--json" takes precedence.
search search [option...] what search [option...] --file what search [option...] --all what By default, search the names, short descriptions, and long descriptions of all locally installed packages for the argument what, interpreted as a (Perl) regular expression.
--file List all filenames containing what.
--all Search everything: package names, descriptions and filenames.
--global Search the TeX Live Database of the installation medium, instead of the local installation.
--word Restrict the search of package names and descriptions (but not filenames) to match only full words.  For example, searching for "table" with this option will not output packages containing the word "tables" (unless they also contain the word "table" on its own).
shell Starts an interactive mode, where tlmgr prompts for commands. This can be used directly, or for scripting. The first line of output is "protocol" n, where n is an unsigned number identifying the protocol version (currently 1).
In general, tlmgr actions that can be given on the command line translate to commands in this shell mode.  For example, you can say "update --list" to see what would be updated. The TLPDB is loaded the first time it is needed (not at the beginning), and used for the rest of the session.
Besides these actions, a few commands are specific to shell mode:
protocol Print "protocol n", the current protocol version.
help Print pointers to this documentation.
version Print tlmgr version information.
quit, end, bye, byebye, EOF Exit.
restart Restart "tlmgr shell" with the original command line; most useful when developing "tlmgr".
load [local|remote] Explicitly load the local or remote, respectively, TLPDB.
save Save the local TLPDB, presumably after other operations have changed it.
get [var] =item set [var [val]] Get the value of var, or set it to val.  Possible var names: "debug-translation", "machine-readable", "no-execute-actions", "require-verification", "verify-downloads", "repository", and "prompt". All except "repository" and "prompt" are booleans, taking values 0 and 1, and behave like the corresponding command line option.  The "repository" variable takes a string, and sets the remote repository location. The "prompt" variable takes a string, and sets the current default prompt.
If var or then val is not specified, it is prompted for.
show Synonym for "info".
uninstall Synonym for remove.
update [option...] [pkg...] Updates the packages given as arguments to the latest version available at the installation source.  Either "--all" or at least one pkg name must be specified.  Options:
--all Update all installed packages except for "tlmgr" itself.  Thus, if updates to "tlmgr" itself are present, this will simply give an error, unless also the option "--force" or "--self" is given.  (See below.)
In addition to updating the installed packages, during the update of a collection the local installation is (by default) synchronized to the status of the collection on the server, for both additions and removals.
This means that if a package has been removed on the server (and thus has also been removed from the respective collection), "tlmgr" will remove the package in the local installation.  This is called ``auto-remove'' and is announced as such when using the option "--list".  This auto-removal can be suppressed using the option "--no-auto-remove" (not recommended, see option description).
Analogously, if a package has been added to a collection on the server that is also installed locally, it will be added to the local installation.  This is called ``auto-install'' and is announced as such when using the option "--list".  This auto-installation can be suppressed using the option "--no-auto-install".
An exception to the collection dependency checks (including the auto- installation of packages just mentioned) are those that have been ``forcibly removed'' by you, that is, you called "tlmgr remove --force" on them.  (See the "remove" action documentation.)  To reinstall any such forcibly removed packages use "--reinstall-forcibly-removed".
If you want to exclude some packages from the current update run (e.g., due to a slow link), see the "--exclude" option below.
--self Update "tlmgr" itself (that is, the infrastructure packages) if updates to it are present. On Windows this includes updates to the private Perl interpreter shipped inside TeX Live.
If this option is given together with either "--all" or a list of packages, then "tlmgr" will be updated first and, if this update succeeds, the new version will be restarted to complete the rest of the updates.
In short:
tlmgr update --self        # update infrastructure only tlmgr update --self --all  # update infrastructure and all packages tlmgr update --force --all # update all packages but *not* infrastructure # ... this last at your own risk, not recommended!
--dry-run Nothing is actually installed; instead, the actions to be performed are written to the terminal.  This is a more detailed report than "--list".
--list [pkg] Concisely list the packages which would be updated, newly installed, or removed, without actually changing anything.  If "--all" is also given, all available updates are listed.  If "--self" is given, but not "--all", only updates to the critical packages (tlmgr, texlive infrastructure, perl on Windows, etc.)  are listed.  If neither "--all" nor "--self" is given, and in addition no pkg is given, then "--all" is assumed (thus, "tlmgr update --list" is the same as "tlmgr update --list --all").  If neither "--all" nor "--self" is given, but specific package names are given, those packages are checked for updates.
--exclude pkg Exclude pkg from the update process.  If this option is given more than once, its arguments accumulate.
An argument pkg excludes both the package pkg itself and all its related platform-specific packages pkg.ARCH.  For example,
tlmgr update --all --exclude a2ping
will not update "a2ping", "a2ping.i386-linux", or any other "a2ping."ARCH package.
If this option specifies a package that would otherwise be a candidate for auto-installation, auto-removal, or reinstallation of a forcibly removed package, "tlmgr" quits with an error message. Excludes are not supported in these circumstances.
This option can also be set permanently in the tlmgr config file with the key "update-exclude".
--no-auto-remove [pkg...] By default, "tlmgr" tries to remove packages which have disappeared on the server, as described above under "--all".  This option prevents such removals, either for all packages (with "--all"), or for just the given pkg names.  This can lead to an inconsistent TeX installation, since packages are not infrequently renamed or replaced by their authors.  Therefore this is not recommend.
--no-auto-install [pkg...] Under normal circumstances "tlmgr" will install packages which are new on the server, as described above under "--all".  This option prevents any such automatic installation, either for all packages (with "--all"), or the given pkg names.
Furthermore, after the "tlmgr" run using this has finished, the packages that would have been auto-installed will be considered as forcibly removed.  So, if "foobar" is the only new package on the server, then
tlmgr update --all --no-auto-install
tlmgr update --all tlmgr remove --force foobar
--reinstall-forcibly-removed Under normal circumstances "tlmgr" will not install packages that have been forcibly removed by the user; that is, removed with "remove --force", or whose installation was prohibited by "--no-auto-install" during an earlier update.
This option makes "tlmgr" ignore the forcible removals and re-install all such packages. This can be used to completely synchronize an installation with the server's idea of what is available:
tlmgr update --reinstall-forcibly-removed --all
--backup --backupdir directory These two options control the creation of backups of packages before updating; that is, backup of packages as currently installed.  If neither options is given, no backup will made. If "--backupdir" is given and specifies a writable directory then a backup will be made in that location. If only "--backup" is given, then a backup will be made to the directory previously set via the "option" action (see below). If both are given then a backup will be made to the specified directory.
You can also set options via the "option" action to automatically make backups for all packages, and/or keep only a certain number of backups.
"tlmgr" always makes a temporary backup when updating packages, in case of download or other failure during an update.  In contrast, the purpose of this "--backup" option is to save a persistent backup in case the actual content of the update causes problems, e.g., introduces an TeX incompatibility.
--no-depends If you call for updating a package normally all depending packages will also be checked for updates and updated if necessary. This switch suppresses this behavior.
--force Force update of normal packages, without updating "tlmgr" itself (unless the "--self" option is also given).  Not recommended.
Also, "update --list" is still performed regardless of this option.
If the package on the server is older than the package already installed (e.g., if the selected mirror is out of date), "tlmgr" does not downgrade.  Also, packages for uninstalled platforms are not installed.
"tlmgr" saves a copy of the "texlive.tlpdb" file used for an update with a suffix representing the repository url, as in "tlpkg/texlive.tlpdb."long-hash-string.  These can be useful for fallback information, but if you don't like them accumulating (e.g., "mirror.ctan.org" resolves to many different hosts, each resulting in a possibly different hash), it's harmless to delete them.
"tlmgr" reads two configuration files: one is system-wide, in "TEXMFSYSCONFIG/tlmgr/config", and the other is user-specific, in "TEXMFCONFIG/tlmgr/config".  The user-specific one is the default for the "conf tlmgr" action.  (Run "kpsewhich -var-value=TEXMFSYSCONFIG" or "... TEXMFCONFIG ..." to see the actual directory names.)
A few defaults corresponding to command-line options can be set in these configuration files.  In addition, the system-wide file can contain a directive to restrict the allowed actions.
In these config files, empty lines and lines starting with # are ignored. All other lines must look like:
key = value
where the spaces are optional but the "=" is required.
The allowed keys are:
"auto-remove", value 0 or 1 (default 1), same as command-line option. "gui-expertmode", value 0 or 1 (default 1). This switches between the full GUI and a simplified GUI with only the most common settings. "gui-lang" llcode, with a language code value as with the command-line option. "no-checksums", value 0 or 1 (default 0, see below). "persistent-downloads", value 0 or 1 (default 1), same as command-line option. "require-verification", value 0 or 1 (default 0), same as command-line option. "update-exclude", value: comma-separated list of packages (no space allowed). Same as the command line option "--exclude" for the action "update". "verify-downloads", value 0 or 1 (default 1), same as command-line option.
The system-wide config file can contain one additional key:
"allowed-actions" action1 [,action,...] The value is a comma-separated list of "tlmgr" actions which are allowed to be executed when "tlmgr" is invoked in system mode (that is, without "--usermode"). This allows distributors to include the "tlmgr" in their packaging, but allow only a restricted set of actions that do not interfere with their distro package manager.  For native TeX Live installations, it doesn't make sense to set this.
The "no-checksums" key needs more explanation.  By default, package checksums computed and stored on the server (in the TLPDB) are compared to checksums computed locally after downloading.  "no-checksums" disables this process.
The checksum algorithm is SHA-512.  Your system must have one of (looked for in this order) the Perl "Digest::SHA" module, the "openssl" program (<https://openssl.org>), the "sha512sum" program (from GNU Coreutils, <https://www.gnu.org/software/coreutils>), or finally the "shasum" program (just to support old Macs).  If none of these are available, a warning is issued and "tlmgr" proceeds without checking checksums. (Incidentally, other SHA implementations, such as the pure Perl and pure Lua modules, are much too slow to be usable in our context.) "no-checksums" avoids the warning.
"tlmgr" and "install-tl" perform cryptographic verification if possible. If verification is performed and successful, the programs report "(verified)" after loading the TLPDB; otherwise, they report "(not verified)".  But either way, by default the installation and/or updates proceed normally.
If a program named "gpg" is available (that is, found in "PATH"), by default cryptographic signatures will be checked: we require the main repository be signed, but not any additional repositories. If "gpg" is not available, by default signatures are not checked and no verification is carried out, but "tlmgr" still proceeds normally.
The behavior of the verification can be controlled by the command line and config file option "verify-repo" which takes one of the following values: "none", "main", or "all". With "none", no verification whatsoever is attempted.  With "main" (the default) verification is required only for the main repository, and only if "gpg" is available; though attempted for all, missing signatures of subsidiary repositories will not result in an error.  Finally, in the case of "all", "gpg" must be available and all repositories need to be signed.
In all cases, if a signature is checked and fails to verify, an error is raised.
Cryptographic verification requires checksum checking (described just above) to succeed, and a working GnuPG ("gpg") program (see below for search method).  Then, unless cryptographic verification has been disabled, a signature file ("texlive.tlpdb.*.asc") of the checksum file is downloaded and the signature verified. The signature is created by the TeX Live Distribution GPG key 0x0D5E5D9106BAB6BC, which in turn is signed by Karl Berry's key 0x0716748A30D155AD and Norbert Preining's key 0x6CACA448860CDC13.  All of these keys are obtainable from the standard key servers.
Additional trusted keys can be added using the "key" action.
Configuration of GnuPG invocation The executable used for GnuPG is searched as follows: If the environment variable "TL_GNUPG" is set, it is tested and used; otherwise "gpg" is checked; finally "gpg2" is checked.
Further adaptation of the "gpg" invocation can be made using the two environment variables "TL_GNUPGHOME", which is passed to "gpg" as the value for "--homedir", and "TL_GNUPGARGS", which replaces the default options "--no-secmem-warning --no-permission-warning".
"tlmgr" provides a restricted way, called ``user mode'', to manage arbitrary texmf trees in the same way as the main installation.  For example, this allows people without write permissions on the installation location to update/install packages into a tree of their own.
"tlmgr" is switched into user mode with the command line option "--usermode".  It does not switch automatically, nor is there any configuration file setting for it.  Thus, this option has to be explicitly given every time user mode is to be activated.
This mode of "tlmgr" works on a user tree, by default the value of the "TEXMFHOME" variable.  This can be overridden with the command line option "--usertree".  In the following when we speak of the user tree we mean either "TEXMFHOME" or the one given on the command line.
Not all actions are allowed in user mode; "tlmgr" will warn you and not carry out any problematic actions.  Currently not supported (and probably will never be) is the "platform" action.  The "gui" action is currently not supported, but may be in a future release.
Some "tlmgr" actions don't need any write permissions and thus work the same in user mode and normal mode.  Currently these are: "check", "help", "list", "print-platform", "print-platform-info", "search", "show", "version".
On the other hand, most of the actions dealing with package management do need write permissions, and thus behave differently in user mode, as described below: "install", "update", "remove", "option", "paper", "generate", "backup", "restore", "uninstall", "symlinks".
