@end table
In addition to these actions @command{guix-package} supports the
following options to query the current state of a profile, or the
availability of packages:
@table @option
@item --list-installed[=@var{regexp}]
@itemx -I [@var{regexp}]
List currently installed packages in the specified profile. When
@var{regexp} is specified, list only installed packages whose name
matches @var{regexp}.
For each installed package, print the following items, separated by
tabs: the package name, its version string, the part of the package that
is installed (for instance, @code{out} for the default output,
@code{include} for its headers, etc.), and the path of this package in
the store.
