Gentoo, два вопроса.

1.Например так:

emerge -av `equery l -p -F '$cp' 'app-portage/*' | uniq`

2.

$ equery l 'app-portage/*'
 * Searching for * in app-portage ...
[IP-] [  ] app-portage/gentoolkit-0.3.0.5:0
[IP-] [  ] app-portage/layman-2.0.0_rc3:0
[IP-] [  ] app-portage/portage-utils-0.9:0

Можно еще -I добавить к equery, чтобы не ставить пакеты, которые и так уже установлены.

equery l 'app-portage/*'

лучше забить на эти говноутилиты, и работать с базой портежа напрямую:

echo /usr/portage/app-portage/* |sed 's,/usr/portage/,,g'

$ for i in {1..3}; do time nice --20 equery l 'app-portage/*'; done
 * Searching for * in app-portage ...

ахдад, пистон не тормозит, и разрабы портежа не быдлокодеры

аяяй, какой фейл, вот поправочка:
