Gentoo utilities file and package info

qlist
all installed packages:

$ qlist -I
app-accessibility/epos
app-accessibility/festival
app-accessibility/flite
app-accessibility/freetts
app-accessibility/speech-tools
app-admin/apache-tools
...


qlist will match regexp on substring.

$ qlist -I perl
app-admin/perl-cleaner
dev-lang/perl
dev-perl/AnyEvent
dev-perl/Authen-SASL
dev-perl/Cairo
...
$ qlist -I perl/.*sq
dev-perl/DBD-mysql


Finding files belonging to an installed package

$ qlist .*perl/.*sq

qfile
The brother of qlist is qfile.
Find which package a file belongs to:

$ qfile /usr/share/doc/DBD-mysql-4.00.5/README.bz2
dev-perl/DBD-mysql (/usr/share/doc/DBD-mysql-4.00.5/README.bz2)


Also works with substring match (but not regexp?)

$ qfile README
app-cdr/cdrtools (/usr/share/doc/cdrtools-2.01.01_alpha57-r1/cdda2wav/README)
app-cdr/cdrtools (/usr/share/doc/cdrtools-2.01.01_alpha57-r1/cdrecord/README)
app-cdr/cdrtools (/usr/share/doc/cdrtools-2.01.01_alpha57-r1/mkisofs/README)
sys-kernel/genkernel (/usr/share/genkernel/modules/README)
sys-kernel/genkernel (/usr/share/genkernel/patches/busybox/1.7.4/README)
sys-kernel/gentoo-sources (/usr/src/linux-2.6.29-gentoo-r5/Documentation/ABI/README)
...


And where to find these tools, and what other tools are there:

$ qlist `qfile -qC qfile` | grep bin
/usr/bin/q
/usr/bin/qatom
/usr/bin/qcache
/usr/bin/qcheck
/usr/bin/qdepends
/usr/bin/qfile
/usr/bin/qglsa
/usr/bin/qgrep
/usr/bin/qlist
/usr/bin/qlop
/usr/bin/qmerge
/usr/bin/qpkg
/usr/bin/qsearch
/usr/bin/qsize
/usr/bin/qtbz2
/usr/bin/quse
/usr/bin/qxpak

Or just try the q command to get descriptions as well. :)

equery
equery does similar things as qlist

equery can find files in installet packages

$ equery f app-portage/gentoolkit | grep bin
/usr/bin
/usr/bin/eclean
/usr/bin/eclean-dist
/usr/bin/eclean-pkg
/usr/bin/epkginfo
/usr/bin/equery
/usr/bin/eread
/usr/bin/euse
/usr/bin/glsa-check
/usr/bin/revdep-rebuild
/usr/sbin


But I don't think the equivalence of qfile is here.

epkginfo is cool though:

$ epkginfo kde-meta
