Package: dctrl-tools Version: 2.24-1 Severity: wishlist Hi,
it would be nice if grep-dctrl supported -f --file like grep:
-f FILE, --file=FILE
Obtain patterns from FILE, one per line. The empty file contains
zero patterns, and therefore matches nothing.
My use case is that I have a list of package names that I want to
extract from a Packages file (-P --file=pkg.list), and inversely, want
to remove from a Packages file (-P --not --file=pkg.list). At the
moment I have to resort to ugly for loops in shell to invoke
grep-dctrl N times, or try to construct a regexp pattern to match the
list of package names at onces, which isn't handy to do in shell
either.
(An alternative solution would be to allow --pattern to be passed
multiple times. I guess if either is implemented, the other isn't much
extra effort.)
Thanks for considering,
Christoph
