NAME

       dgrep, degrep, dfgrep, dzgrep -- grep through files belonging to an installed Debian
       package

SYNOPSIS

       dgrep [most grep options] pattern package...

       dgrep --help

DESCRIPTION

       dgrep invokes grep(1) on each file in one or more installed Debian packages.

       It passes the package argument(s) to dglob(1) to retrieve a list of files in those
       packages. It uses dglob's substring pattern matching for the package names.

       If dgrep is invoked as degrep, dfgrep or dzgrep, etc. then grep(1) with option "-E" or
       "-F" respectively the command zgrep(1) is used instead of grep(1).

OPTIONS

       dgrep supports most of grep(1)'s options. Please refer to your grep(1) 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.

   Options of grep that are not supported by dgrep
       -r, --recursive, -d recurse, --directories=recurse
       -d read, --directories=read
           dgrep searches only in the "normal" files of a package. It skips all directories and
           symlinks. Therefore the options of grep that are specific to directories are not
           supported.
