Managing Packages

foo is the name of the program you wish to use. It's just a random word, which you replace with what you're actually performing the operation on.

* Emerges program foo

emerge foo

* Lists all the programs that would be emerged if you installed foo, plus all their USE flags and the size of the downloads needed

emerge -pv foo

* Lists all the programs needed to install foo plus all their USE flags and the size of the downloads needed and asks if you want to install them

emerge -av foo

* Search packages for a program whose name contains 'foo' (for faster searches see TIP Speed up searches in portage)

emerge -s foo

* Search packages for a program whose description contains 'foo' (Warning! This may take a while - see link above)

emerge -S foo

* Updates the portage tree with the latest ebuilds

emerge --sync

* Lists all the programs and their dependencies which need to be upgraded and asks if you want to install them

emerge -avuD world

* Lists all system programs and their dependencies which need to be upgraded and asks if you want to install them

emerge -avuD system

* Uninstall a program

emerge -aC foo

* Emerge a specific version of a package
emerge =foo-bar/foo-1.2.3-r4
emerge =foo-1.2.3-r4 (if package name is not ambiguous)

* Evil tool for updating config files

etc-update

* Better tool for updating config files

dispatch-conf

echo "foo-bar/foo-1.2.3-r4 ~x86" >> /etc/portage/package.keywords
emerge foo

* Mask a package to stop it from being installed/upgraded

echo foo-bar/foobar >> /etc/portage/package.mask

emerge -vva foo
