[gentoo-user] Before doing something wrong

[Meino Christian Cramer]

Hi,

 short question: Is

	   emerge --clean

 the right way to remove unused stuff from my system /without/
 removing files from /usr/portage/ and below ?

 Keep hacking!

If you installed a program that you no longer need, you can do a emerge
-C <package name> and it will remove it for you.  The -C is the same as
--clean by the way.

That said, be very careful with that.  If you remove some things it can
break portage, gcc or some other program that the system uses.  I would
strongly recommend you do a equery depends <package name> to make sure
you do not remove something that will break things.

Hope that helps and keeps you from hurting at the same time.  It's easy
done.

Nope, -C is the short for --unmerge. -c would be --clean.

And --clean cleans a package, that means when you have two versions of a
non slotted ebuild installed. It automatically happens after you upgrade
a package, first the new version is installed parallel to the existing
one, then the old one is "cleaned out".

You should never need a manual --clean :) But it should never break
anything, which --unmerge can.

That's correct.  That shift key sure does make a difference don't it? 
Still, be careful with what you remove.

Correct.

This is absolutely false. --clean has no effect on unslotted packages. It is 
equivalent to --prune except that it only removes old slots if nothing 
depends on them. Read `man emerge`.

You mean 'emerge --depclean --pretend'?  Heed the warning and do 
an 'emerge -uND world' first.  And if you're not feeling brave, 
quickpkg the stuff that's going to be removed.
