       apt-file - APT package searching utility -- command-line interface


       apt-file [ options ] [ action ] [ pattern ]

       apt-file -f [ options ] search [ file ... ]

       apt-file -D [ options ] search [ binary-packet.deb ... ]


       apt-file  is  a  command  line  tool  for  searching files in packages for the APT package
       management system.

       Some actions are required to run the search:

       update Resynchronize the package contents from their sources. The lists of the contents of
              packages  are fetched from the location(s) specified in /etc/apt/sources.list. This
              command attempts to fetch the Contents-<ARCH>.gz files  from  remote  sources.  For
              downloading  these  uses  either  the  curl  or  wget commands as specified in apt-

       search Search in which package a file is included. A list of all packages  containing  the
              pattern pattern is returned.

              apt-file  will  only search for filenames, not directory names.  This is due to the
              format of the Contents files it searches.

       find   Alias for search.

       list   List the contents of a package matching the pattern pattern. This  action  is  very
              close  to  the  dpkg -L command except the package does not need to be installed or

       show   Alias for list.

       purge  remove all Contents-* files from the cache directory.


          --cache | -c cache-directory
              Sets the cache directory to cache-directory instead of its default. If executed  as
              non-root   user,   the   default   is   $HOME/.cache/apt-file   with  fall-back  to
              /var/cache/apt/apt-file. The latter is also the default if apt-file  is  called  as

          --verbose | -v
              Run apt-file in verbose mode.

          --cdrom-mount | -d cdrom-mount-point
              Use cdrom-mount-point instead of apt's.

          --non-interactive | -N
              Skip  schemes  that  are  listed in the interactive line in apt-file.conf.  This is
              useful if you want to call 'apt-file update' in cron jobs and skip all schemes that
              may require user input.

          --ignore-case | -i
              Ignore case when searching for pattern.

          --regexp | -x
              Treat pattern as a (perl) regular expression. See perlreref(1) for details. Without
              this option, pattern is treated as a literal string to search for.

          --architecture | -a architecture
              Sets architecture to architecture. This option is useful if you  search  a  package
              for  a different architecture from the one installed on your system.  It determines
              how the $ARCH variable in sources.list is expanded (but it does not  influence  the
              search in any other way).

          --sources-list | -s sources.list
              Sets   the   sources.list   file   to   a   different   value   from   its  default

          --package-only | -l
              Only display package name; do not display file names.

          --from-file | -f
              Read patterns from the given file(s), one per line.  Use -f - for stdin.   This  is
              much faster than invoking apt-file many times.

          --from-deb | -D
              Use  contents  of the given .deb archives(s) as patterns.  Useful for searching for
              file conflicts with other packages.  Implies -F.

          --fixed-string | -F
              Do not expand search pattern with generic characters at pattern's start and end.

          --dummy | -y
              Run in dummy mode (no action).

          --help | -h
              Display a short help screen.


       The apt-file configuration file can be found in /etc/apt/apt-file.conf.

       A string expansion is done on several values. See the string expansion section.

              This variable describes how cached files will be named.

       http | ftp | ssh | rsh | file | cdrom
              Defines the commands used to fetch files.

       A sources.list entry is defined as:

              deb uri dist component1 component2 ...

       A uri is defined as:


       <host> replace with the hostname

       <port> replace with the port number

       <uri>  replace with full uri

       <path> replace with full path (relative to / on the host)

       <dist> replace with distribution name

       <comp> replace with component name

              replace with cache directory

       <dest> replace with destination expanded value.

              replace with cdrom-mount-point.

       auto-apt(1),   apt-cache(8),   apt-cdrom(8),   dpkg(8),    dselect(8),    sources.list(5),

       The cdrom backend has not been tested.

       Non-release lines in sources.list are not handled by apt-file.

       There  is only one Contents file per distribution that contains all components (i.e. main,
       contrib, and  non-free).  Threrefore,  apt-file  will  display  search  results  from  all
       components, even if not all components are included in the sources.list file.

       When  a  new line has been added to the sources.list and apt-file update has not been run,
       apt-file does not print a warning message.

       Complex regular expressions that match the leading slash may  not  work  correctly.  As  a
       workaround,  try to pull the leading slash to the beginning of the regular expression. For
       example, use "/(usr/bin/vim|sbin/lvm)" instead of "/usr/bin/vim|/sbin/lvm".
