You guys are all giving good info but let me make a quick clarification of what I'm trying to do. I'm not just moving the individual mp3s. I'm trying to move an entire cd - or entire dir that contains a bunch of mp3s. for example

$mp3concat -s 700 "Queen/" "RATT/" "R.E.M/" "RobbieWilliams/" "Rolling Stones/" "Rush/"
or
mp3concat -s 700 `ls |awk '{print "\""$0"\""}'`

As long as I quote it on the command line $file seems to have the correct value but the move still doesn't work.
