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.
- -S, --sync
Search the sync databases for provided targets.
- -Q, --query
Search the local database for provided targets. This is the default behavior.
- -s, --search
Search for packages matching the strings specified by targets. This is a boolean AND query and regex is allowed.
- -g, --group
Return packages matching the specified targets as package groups.
- -1, --readone
Stop searching after the first result. This only has an effect on -S operations without -s.
- -d, --delim <string>
Separate each package with the specified string. The default value is a newline character.
- -l, --listdelim <string>
Separate each list item with the specified string. Lists are any interpreted sequence specified with a capital letter. The default value is two spaces.
- -t, --timefmt <format>
Output time described by the specified format. This string is passed directly to strftime(3). The default format is %c.
- -v, --verbose
Output more. `Package not found' errors will be shown, and empty field values will display as 'None'.
- -h, --help
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) %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).
