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. 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).

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.
