expac - alpm data extraction utility

Usage: expac [options] <format> targets...

expac is a data extraction tool for alpm databases. It features printf-like flexibility and aims to be used as a simple tool for other pacman based utilities which don't link against the library. It uses pacman.conf as a config file for locating and loading your local and sync databases.

Targets are provided on the command line, and can be specified by simple name, or in repo/pkg format if the --sync option is used.

Search the sync databases for provided targets.

Search the local database for provided targets. This is the default behavior.

Search for packages matching the strings specified by targets. This is a boolean AND query and regex is allowed.

Return packages matching the specified targets as package groups.

Stop searching after the first result. This only has an effect on -S operations without -s.

Separate each package with the specified string. The default value is a newline character.

Separate each list item with the specified string. Lists are any interpreted sequence specified with a capital letter. The default value is two spaces.

Output time described by the specified format. This string is passed directly to strftime(3). The default format is %c.

Output more. `Package not found' errors will be shown, and empty field values will display as 'None'.

Display the help message and quit.

The format argument allows the following interpreted sequences:

  %B    backup files

  %C    conflicts with

  %D    depends on

  %E    depends on (no version strings)

  %F    files (only with -Q)

  %G    groups

  %L    licenses

  %N    required by

  %O    optional deps

  %o    optional deps (no descriptions)

  %P    provides

  %R    replaces

  %S    provides (no version strings)

  %a    architecture

  %b    build date

  %d    description

  %f    filename (only with -S)

  %g    base64 encoded PGP signature (only with -S)

  %h    sha256sum

  %i    has install scriptlet (only with -Q)

  %k    download size (only with -S)

  %l    install date (only with -Q)

  %m    install size

  %n    package name

  %p    packager name

  %r    repo

  %s    md5sum

  %u    project URL

  %v    version

  %w    install reason

  %!    result number (auto-incremented counter, starts at 0)

  %%    literal %

Note that for any lowercase tokens aside from %m and %k, full printf support is allowed, e.g. %-20n. This does not apply to any list based, date, or numerical output.

Standard backslash escape sequences are supported, as per printf(1).
