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


       dgrep [most grep options] pattern package...

       dgrep --help


       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. You can use POSIX regular expressions for the package names.

       If dgrep is invoked as degrep, dfgrep or dzgrep then egrep(1), fgrep(1) or zgrep(1) is
       used instead of grep(1).


       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. Therefor the options of grep that are specific to directories are not
