Uninstalling Drivers: pacman -Rsu ?

trusktr · 2010-02-21 03:27:59

Hey, once I install a driver, if it turns out to be the wrong one, can I just uninstall it and return to how my system was previously?

Say with the pacman -Rsu command?

Just -Rs is fine

Thanks Allan. What;s the difference?

"man pacman" is you r friend:

-s, --recursive
Remove each target specified including all of their dependencies, provided that (A) they are not required by other packages; and (B) they were not explicitly installed by the user. This operation is recursive and analogous to a backwards --sync operation, and helps keep a clean system without orphans. If you want to omit condition (B), pass this option twice.

-u, --unneeded
Removes the targets that are not required by any other packages. This is mostly useful when removing a group without using the -c option, to avoid breaking any dependencies.

So if I don't use the 'u' option, then perhaps it might leave some packages/apps/targets that essentially won't be used for anything, save for their possible handyness in the future?

-s command:
"Remove each target specified including all of their dependencies"

then have a look at condition (A) of the -s command:
"provided that (A) they are not required by other packages"

compare this to -u:
"Removes the targets that are not required by any other packages."

and than condition (B) of the -s command:
"and (B) they were not explicitly installed by the user."

So you aren't left with any orphans if you use -s and not -u.

Hey sorry, Jack in my previous comment i meant 's', not 'u'.

So just using and 's' will then leave packages/apps that perhaps might not even be used for anything, whereas these packages will be deleted by using 'u'.

So if i want my system to be cleaner, then perhaps I should just include the 'u', right?

Oh, and by "explicitly installed" i'm assuming this means installed without the use of pacman, right?

Wrong. Please don't make assumptions without doing the necessary research - in this case, a thorough reading of the pacman man page will help.

Alright, will do. Thanks!
