NAME
dpkg-query - a tool to query the dpkg databaseSYNOPSIS
dpkg-query [option...] commandDESCRIPTION
dpkg-query is a tool to show information about packages listed in the dpkg database.COMMANDS
- -l, --list package-name-pattern...
- List packages matching given pattern. If no package-name-pattern is given, list all packages in /var/lib/dpkg/status, excluding the ones marked with state purge. Normal shell wildchars are allowed in package-name-pattern. Please note you will probably have to quote package-name-pattern to prevent the shell from performing filename expansion. For example this will list all package names starting with ``libc6'':
dpkg-query -l 'libc6*'
The output format of this option is not configurable, but varies automatically to fit the terminal width. It is intended for human readers, and is not easily machine-readable. See -W (--show) and --showformat for a way to configure the output format.
- -W, --show package-name-pattern...
- Just like the --list option this will list all packages matching the given pattern. However the output can be customized using the --showformat option. The default output format gives one line per matching package, each line having the name and installed version of the package, separated by a tab.
- -s, --status package-name...
- Report status of specified package. This just displays the entry in the installed package status database.
- -L, --listfiles package-name...
- List files installed to your system from package-name. However, note that files created by package-specific installation-scripts are not listed.
- -S, --search filename-search-pattern...
- Search for a filename from installed packages. All standard shell wildchars can be used in the pattern. This command will not list extra files created by maintainer scripts, nor will it list alternatives.
- -p, --print-avail package-name...
- Display details about package-name, as found in /var/lib/dpkg/available.
- -h, --help
- Show the usage message and exit.
- --version
- Show the version and exit.
- --license, --licence
- Show the copyright licensing terms and exit.
OPTIONS
- --admindir=dir
- Change the location of the dpkg database. The default location is /var/lib/dpkg.
- -f, --showformat=format
- This option is used to specify the format of the output --show will produce. The format is a string that will be output for each package listed.
In the format string, "\" introduces escapes:
\n newline \r carriage return \t tab
"\" before any other character suppresses any special meaning of the following character, which is useful for "\" and "$".
Package information can be included by inserting variable references to package fields using the syntax "${field[;width]}". Fields are printed right-aligned unless the width is negative in which case left alignment will be used. The following fields are recognised:
Architecture Bugs Conffiles Config-Version Conflicts Breaks Depends Description Enhances Essential Filename Homepage Installed-Size MD5sum MSDOS-Filename Maintainer Origin Package Pre-Depends Priority Provides Recommends Replaces Revision Section Size Source Status Suggests Tag Version
The default format string is "${Package}\t${Version}\n". Actually, all other fields found in the status file (i.e. user defined fields) can be requested, too. They will be printed as-is, though, no conversion nor error checking is done on them. To get the name of the dpkg maintainer and the installed version, you could run:
dpkg-query -W -f='${Package} ${Version}\t${Maintainer}\n' dpkg
ENVIRONMENT
- COLUMNS
- This setting influences the output of the --list option by changing the width of its output.
