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.
