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:
- Alias for search.
- 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 fetched.
- remove all Contents-* files from the cache directory.
Search in which package a file is included. A list of all
packages containing the pattern pattern
apt-file will only search for filenames, not directory names. This is due to the format of the Contents files it searches.
- Alias for list.
- 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-file.conf.
- -a, --architecture 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).
- -c, --cache 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 root.
- -d, --cdrom-mount cdrom-mount-point
- Use cdrom-mount-point instead of apt's.
- -D, --from-deb
- Use contents of the given .deb archives(s) as patterns. Useful for searching for file conflicts with other packages. Implies -F.
- -f, --from-file
- Read patterns from the given file(s), one per line. Use - as filename for stdin. If no files are given, then the list will be read from stdin. This is much faster than invoking apt-file many times.
- -F, --fixed-string
- Do not expand search pattern with generic characters at pattern's start and end.
- -i, --ignore-case
- Ignore case when searching for pattern.
- -l, --package-only
- Only display package name; do not display file names.
- -N, --non-interactive
- 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.
- -s, --sources-list sources.list
- Sets the sources.list file to a different value from its default /etc/apt/sources.list.
- -v, --verbose
- Run apt-file in verbose mode.
- -x, --regexp
- 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.
- -y, --dummy
- Run in dummy mode (no action).
- -h, --help
- 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:
- replace with the hostname
- replace with the port number
- replace with full uri
- replace with full path (relative to / on the host)
- replace with distribution name
- replace with component name
- replace with cache directory
- replace with destination expanded value.
- replace with cdrom-mount-point.
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".
