# dpkg-genchanges

## NAME



           dpkg-genchanges - generate Debian .changes files
    


## SYNOPSIS



           **dpkg-genchanges**[_option_...]
    


## DESCRIPTION



           **dpkg-genchanges** reads information from an unpacked and built
           Debian source tree and from the files it has generated and
           generates a Debian upload control file (**.changes** file).
    


## OPTIONS



           **--build=**_type_
               Specifies the build _type_ from a comma-separated list of
               components (since dpkg 1.18.5).
    
               The allowed values are:
    
               **source**
                   Upload the source package.
    
               **any** Upload the architecture specific binary packages.
    
               **all** Upload the architecture independent binary packages.
    
               **binary**
                   Upload the architecture specific and independent binary
                   packages.  This is an alias for **any,all**.
    
               **full**
                   Upload everything.  This is alias for **source,any,all** , and
                   the same as the default case when no build option is
                   specified.
    
           **-g** Equivalent to **--build=source,all**(since dpkg 1.17.11).
    
           **-G** Equivalent to **--build=source,any**(since dpkg 1.17.11).
    
           **-b** Equivalent to **--build=binary** or **--build=any,all**.
    
           **-B** Equivalent to **--build=any**.
    
           **-A** Equivalent to **--build=all**.
    
           **-S** Equivalent to **--build=source**.
    
           The **-s** _x_ options control whether the original source archive is
           included in the upload if any source is being generated (i.e.  **-b**
           or **-B** haven't been used).
    
           **-si** By default, or if specified, the original source will be
               included only if the upstream version number (the version
               without epoch and without Debian revision) differs from the
               upstream version number of the previous changelog entry.
    
           **-sa** Forces the inclusion of the original source.
    
           **-sd** Forces the exclusion of the original source and includes only
               the diff.
    
           **-v** _version_
               Causes changelog information from all versions strictly later
               than _version_ to be used.
    
           **-C** _changes-description_
               Read the description of the changes from the file _changes-_
               _description_ rather than using the information from the source
               tree's changelog file.
    
           **-m** _maintainer-address_
               Use _maintainer-address_ as the name and email address of the
               maintainer for this package, rather than using the information
               from the source tree's control file.
    
           **-e** _maintainer-address_
               Use _maintainer-address_ as the name and email address of the
               maintainer for this upload, rather than using the information
               from the source tree's changelog.
    
           **-V** _name_**=**_value_
               Set an output substitution variable.  See deb-substvars(5) for
               a discussion of output substitution.
    
           **-T** _substvars-file_
               Read substitution variables in _substvars-file_ ; the default is
               **debian/substvars**.  No variable substitution is done on any of
               the fields that are output, except for the contents extracted
               from each binary package **Description** field (since dpkg
               1.19.0), however the special variable _Format_ will override the
               field of the same name.  This option can be used multiple
               times to read substitution variables from multiple files
               (since dpkg 1.15.6).
    
           **-D** _field_**=**_value_
               Override or add an output control file field.
    
           **-U** _field_
               Remove an output control file field.
    
           **-c** _controlfile_
               Specifies the main source control file to read information
               from.  The default is **debian/control**.
    
           **-l** _changelog-file_
               Specifies the changelog file to read information from.  The
               default is **debian/changelog**.
    
           **-f** _files-list-file_
               Read the list of files to be uploaded here, rather than using
               **debian/files**.
    
           **-F** _changelog-format_
               Specifies the format of the changelog.  See
               dpkg-parsechangelog(1) for information about alternative
               formats.
    
           **-u** _upload-files-dir_
               Look for the files to be uploaded in _upload-files-dir_ rather
               than **..**(**dpkg-genchanges** needs to find these files so that it
               can include their sizes and checksums in the **.changes** file).
    
           **-q** Usually **dpkg-genchanges** will produce informative messages on
               standard error, for example about how many of the package's
               source files are being uploaded.  **-q** suppresses these
               messages.
    
           **-O**[_filename_]
               Print the changes file to standard output (the default) or to
               _filename_ if specified (since dpkg 1.18.5).
    
           **-?** , **--help**
               Show the usage message and exit.
    
           **--version**
               Show the version and exit.
    


## ENVIRONMENT



           **DEB_HOST_ARCH**
               Sets the host architecture.
    
           **DPKG_COLORS**
               Sets the color mode (since dpkg 1.18.5).  The currently
               accepted values are: **auto**(default), **always** and **never**.
    
           **DPKG_NLS**
               If set, it will be used to decide whether to activate Native
               Language Support, also known as internationalization (or i18n)
               support (since dpkg 1.19.0).  The accepted values are: **0** and **1**
               (default).
    


## FILES



           **debian/files**
               The list of generated files which are part of the upload being
               prepared.  **dpkg-genchanges** reads the data here when producing
               a **.changes** file.
