=head1 NAME dgrep, degrep, dfgrep, dzgrep -- grep through files belonging to an installed Debian package =head1 SYNOPSIS B [I] I I... B B<--help> =head1 DESCRIPTION B invokes grep(1) on each file in one or more installed Debian packages. It passes the I argument(s) to dglob(1) to retrieve a list of files in those packages. You can use POSIX regular expressions for the package names. If B is invoked as B, B or B then egrep(1), fgrep(1) or zgrep(1) is used instead of B. =head1 OPTIONS B supports most of grep(1)'s options. Please refer to your B documentation (i.e. the manpage or the texinfo manual) for a complete listing. Only a few options are excluded because they do not conform with the intended behaviour, see the list below. =head2 Options of grep that are not supported by dgrep =over 4 =item B<-r>, B<--recursive>, B<-d> I, B<--directories>=I =item B<-d> I, B<--directories>=I B searches only in the "normal" files of a package. It skips all directories and symlinks. Therefor the options of grep that are specific to directories are not supported. =back =head1 AUTHOR Matt Zimmerman This manpage was written by Frank Lichtenheld . =head1 COPYRIGHT AND LICENCE Copyright (C) 2001 Matt Zimmerman .
