Hello!

It would be nice if pacman could handle package cleaning with arguments in regex way.

Example usage:
pacman -Sc alsa* -> remove the files from package cache dir which start with 'alsa'
pacman -Sc mpd-0.15.2 mc-4.6.1 -> remove mpd-0.15.2-1-$arch.pkg.tar.gz and mc-4.6.1-5-$arch.pkg.tar.gz. (you could combine with =, =>, =< too e.g.)

Thanks in advance.
This task depends upon

Wouldn't it be much better the other way - i.e. selecting packages too keep?

Anyway, I know what Dan is going to say to this. Same as he always says to advanced cache cleaning... "pacman is not a cache cleaning tool".

Allan knows me too well. :)

Considering what you said is simply an alias for "rm /var/cache/pacman/pkg/<globexpression>", I see very little added value here.

pacman -Scc is a simple rm procedure too e.g., in last case you could alias it without being a pacman option, maybe I'm wrong.

I oversimplified slightly in that if you have multiple cache directories, -Sc and -Scc will operate across all of them.
Comment by Laszlo Papp (djszapi) - Sunday, 20 September 2009, 17:44 GMT
Yeah, but you could alias it in that case too, without being a separate pacman option. In this regard it doesn't count how many cache directory exists.

Many people have suggested changes to the cache cleaning but they all tend to be rejected. Perhaps a general repo cleaning utility could be included in contrib if someone ever wrote one...

+1 to Allan's suggestion.

As a side note, I realized there was still one TODO in our current cache cleaning code, so I will have a patch for that shortly...
