Changing to pacman-contrib as this script has moved from the pacman codebase. I'm not sure who maintains this now, but it is an Arch project: https://git.archlinux.org/pacman-contrib.git/

The default of 3 is when you do not pass -k. If you specify -k in your args, it needs to have a value along with, as the error message says.

Then I misinterpreted the help text.
Still, it seems weird that paccache then obviously keeps stuff even if I do not supply the --keep argument, and thus, if I do not want to keep anything I'd have to tell it to keep stuff with an amount of zero, right?

If you accepted all of the defaults (and assuming default keep was 0), then running 'paccache -r' would be no different than 'rm *'. Defaulting to something greater than 0 is a sane and safe default.
Comment by Richard Neumann (rne) - Tuesday, 20 June 2017, 13:38 GMT
I still don't think so, but I agree, that changing the default behaviour would be an unnecessary hassle most likely braking several user's scripts.
Since I now understand how to use paccache for my purpose you may want to close this as "not a bug" as a case of PEBKAC. ;)
