=head1 NAME

dglob - Expand package names or files matching a pattern

=head1 SYNOPSIS

B<dglob> [B<-a>] I<pattern>

B<dglob> [B<-0>] B<-f> I<pattern>

=head1 DESCRIPTION

B<dglob> searches for packages whose names match a pattern, and can
either output their names, or a list of the files they contain. Per
default, only installed packages are matched, unless you use the B<-a>
option (see L<"OPTIONS">). The list of packages is written to stdout,
one package per line.

grep-dctrl(1) is used to search the list of packages, so you should
refer to its documentation for information on how patterns are
matched.  By default, all packages whose name contains the given
string will be matched, but several options are available to modify
this behavior (see L<"OPTIONS">).

If you use dglob with the B<-f> option, all files in the matched packages
are listed instead of their names. Only existing, plain (i.e. no symlinks,
directories or other special ones) files are listed. The filenames are
written to stdout, one file per line. You can use the B<-0> option to
get the filenames separated by '\0' instead of a newline.

=head1 OPTIONS

B<dglob> suppports the following options:

=over 4

=item B<-a>

Search through all available packages, not just installed ones.

=item B<-f>

List all files in the matched packages. This list only installed (i.e. 
locallly existing) files from installed packages, so using it together
with B<-a> is rather pointless.

=item B<-0>

When listing files (with B<-f>) use '\0' as a separator instead of
a newline. When specified without B<-f>, this options does nothing.

=item B<-r>, B<-e>, B<-i>, B<-X>, B<-v>

These options are passed directly to grep-dctrl(1) to modify how the
pattern is matched.  See grep-dctrl(1).
