Well, seems the latest version of gentoolkit removed the venerable "qpkg" in favour of.. eewrhg. equery.
equery is slow, appears bloated in its output, likes fancy colours just as much as qpkg did, and appears to be fond of polluting a simple "list" (oh sorry, "files" ) output with several lines of headers, even when its told to be quiet.
Did I mention that its slow?
so, here's a ++ for our old friend, app-portage/epm its fast and doesn't try to be overly smart.
where you with equery have to do :
equery -C -q l '.*gnome*.'
* installed packages
[I--] [ ] app-admin/gnome-system-tools-1.2.0 (0)
[I--] [ ] app-pda/gnome-pilot-conduits-2.0.12 (0)
[I--] [ ] app-pda/gnome-pilot-2.0.12 (0)
..
to get a non-coloured output, with epm it is :
epm -qa |grep gnome . Though bear in mind, this doesn't match category, only package name.
However.. its fast and appears consistent. I like that.
