Gentoo Cheatsheet

Java install

ls /usr/portage/dev-java/sun-jdk/
emerge -av =dev-java/sun-jdk-
java-config -L
java-config -S 1
/usr/sbin/env-update && source /etc/profile

Emerge and Equery

Taken from here

emerge brings in new packages. equery looks at the package database.

update repository:
emerge –sync
install package with query
emrge -av sun-jdk
start with this software
emerge links wget htop
emerge …
manipulate package database
emerge -NDtu world
–update packages and packages that depend on updated packages (–deep) in the world list. Give output in –tree format. Consider packages changed if their USE flags have changed (–newuse, -N) Add –pretend (-p) to just see what it will do first.
emerge –skipfirst …
skip first pkg on a rebuild; very useful if something doesn’t work
equery …
query package database
equary belongs
who owns these files?
equery list
list packages on system


Taken from here

Do this whenever you want a steaming pile of fresh packages.

# emerge --sync
# emerge --update system
# etc-update
if necessary
# emerge --update world

I have seen Meddle to do it this way

emerge –newuse –deep –update world
emerge –ask –verbose coreutils
emerge –resume

Fix the mktemp / coreutils block in Gentoo

Looks like mktemp is now provided by coreutils. No wonder. This block has been bugging me (read: I’ve been ignoring it) for months.

To fix just unmerge mktemp and update coreutils.

Update: Same for the setarch / util-linux block should you come across it. Unmerge setarch.

  1. The mktemp/coreutils block will be handled automatically in newer portage versions.
