Normally when I have to repeat a number of commands, I write a bash/sh-script. 
That also helps in remembering. (One of the basic principles of programming 
and administration, dry - don't repeat yourself.)

Only in this case of conversion/copying of files the resulting script would 
have been to complicated for a ten-minutes hack (several subdirs with source-
files of ogg, mp3 and more as input converted to a target dir, preserving the 
directory-structure while converting all files to mp3 when the target is the 
mp3-only player and convert all to mp3 or ogg when the target is the mobile 
player - thats the features that script would have needed), so I searched 
aptitude for something and found the converter. It isn't as flexible as the 
ideas I had for a script, but was faster to "write"...

Have fun,
