## DESCRIPTION



           This manual page describes the **restorecon** program.
    
           This program is primarily used to set the security context
           (extended attributes) on one or more files.
    
           It can also be run at any other time to correct inconsistent
           labels, to add support for newly-installed policy or, by using the
           **-n** option, to passively check whether the file contexts are all
           set as specified by the active policy (default behavior).
    
           If a file object does not have a context, **restorecon** will write
           the default context to the file object's extended attributes. If a
           file object has a context, **restorecon** will only modify the type
           portion of the security context.  The **-F** and **-U** options will force
           a replacement of the entire context.
    
           If a file is labeled with **customizable** SELinux type (for list of
           customizable types see
           /etc/selinux/{SELINUXTYPE}/contexts/customizable_types),
           restorecon won't reset the label unless the -F option is used.
    
           It is the same executable as **setfiles** but operates in a slightly
           different manner depending on its argv[0].
    


## OPTIONS



           **-e** _directory_
                  exclude a directory (repeat the option to exclude more than
                  one directory, Requires full path).
    
           **-f** _infilename_
                  _infilename_ contains a list of files to be processed. Use
                  “**-** ” for **stdin**.
    
           **-F** Force reset of context to match file_context for
                  customizable files, and the default file context, changing
                  the user, role, range portion as well as the type.
    
           **-U** In addition to the type portion also change the user and
                  role portions, but not the range portion.
    
           **-h, -?** display usage information and exit.
    
           **-i** ignore files that do not exist.
    
           **-I** ignore digest to force checking of labels even if the
                  stored SHA1 digest matches the specfiles SHA1 digest. The
                  digest will then be updated provided there are no errors.
                  See the **NOTES** section for further details.
    
           **-D** Set or update any directory SHA1 digests. Use this option
                  to enable usage of the _security.sehash_ extended attribute.
    
           **-m** do not read **/proc/mounts** to obtain a list of non-seclabel
                  mounts to be excluded from relabeling checks.  Setting this
                  option is useful where there is a non-seclabel fs mounted
                  with a seclabel fs mounted on a directory below this.
    
           **-n** don't change any file labels (passive check).  To display
                  the files whose labels would be changed, add **-v**.
    
           **-o** _outfilename_
                  Deprecated - This option is no longer supported.
    
           **-p** show progress by printing the number of files in 1k blocks
                  unless relabeling the entire OS, that will then show the
                  approximate percentage complete. Note that the **-p** and **-v**
                  options are mutually exclusive.
    
           **-R, -r** change files and directories file labels recursively
                  (descend directories).
    
           **-v** show changes in file labels. Multiple -v options increase
                  the verbosity. Note that the **-v** and **-p** options are mutually
                  exclusive.
    
           **-W** display warnings about entries that had no matching files
                  by outputting the selabel_stats(3) results.
    
           **-0** the separator for the input items is assumed to be the null
                  character (instead of the white space).  The quotes and the
                  backslash characters are also treated as normal characters
                  that can form valid input.  This option finally also
                  disables the end of file string, which is treated like any
                  other argument.  Useful when input items might contain
                  white space, quote marks or backslashes.  The **-print0**
                  option of GNU **find** produces input suitable for this mode.
    
           **-x** prevent **restorecon** from crossing file system boundaries.
    
           **-T** _nthreads_
                  use up to _nthreads_ threads.  Specify 0 to create as many
                  threads as there are available CPU cores; 1 to use only a
                  single thread (default); or any positive number to use the
                  given number of threads (if possible).
    


## ARGUMENTS



                  _pathname_ ...  The pathname for the file(s) to be relabeled.
    


## NOTES



           1.  **restorecon** by default does not operate recursively on
               directories. Paths leading up the final component of the
               file(s) are canonicalized using realpath(3) before labeling.
    
           2.  If the _pathname_ specifies the root directory and the **-vR** or
               **-vr** options are set and the audit system is running, then an
               audit event is automatically logged stating that a "mass
               relabel" took place using the message label **FS_RELABEL**.
    
           3.  To improve performance when relabeling file systems
               recursively (i.e. the **-R** or **-r** option is set), the **-D** option
               to **restorecon** will cause it to store a SHA1 digest of the
               default specfiles set in an extended attribute named
               _security.sehash_ on each directory specified in _pathname_ ...
               once the relabeling has been completed successfully. These
               digests will be checked should **restorecon -D** be rerun with the
               same _pathname_ parameters. See selinux_restorecon(3) for
               further details.
    
               The **-I** option will ignore the SHA1 digest from each directory
               specified in _pathname_ ...  and provided the **-n** option is NOT
               set and recursive mode is set, files will be relabeled as
               required with the digests then being updated provided there
               are no errors.
    


## EXAMPLE



           Fix labeling of /var/www/ including all sub-directories and list all context changes
           # restorecon -rv /var/www/
           List mislabeled files in user home directory and what the correct label should be
           # restorecon -nvr ~
           Fix labeling of files listed in file_list file, ignoring any that do not exist
           # restorecon -vif file_list
