Add-on: [CS-FSLUG] Alarm for command-line processes?

[Jukka Y]

Hi! Doesn't "mogrify -format pnm *.jpg" convert all jpg's at the current 
directory to pnm. It is fine, but then conversion takes a lot of space (pnm's 
are almost 7-times bigger than jpg's). I think that in order to keep 
conversion "small", I need a script to processes files one by one.

Blessings,
Jukka
