Grep through files belonging to an installed debian package
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 \s-1POSIX\s0 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.
dgrep supports most of grep\|(1)'s options. Please refer to your grep 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.
dgrep searches only in the \*(L"normal\*(R" files of a package. It skips all directories and symlinks. Therefor the options of grep that are specific to directories are not supported.
