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