That actually did fix the issue. Instead of: for f in `ls *.mp3` I used for f in `/bin/ls *.mp3` but your example for file in '`ls --color=never`' is good. So there are some issues with ls and color. This I think is interesting. Not sure whether it qualifies as a bug. I should not have given up on you. I was also wrong in my usage of the reply function. There were communication issues. Your behaviour was similar to a troll. Why would you tell me "set -x" when I mentioned that I have done shell programming for > 12 years? Why would you ignore the fact that I told you I am meticulous with my environment? What a troll does is deliberately misread information so that they can tell you things that you already know. A troll never admits that they are wrong, and they tell you that you are doing things wrong. You know that there are a million ways to program. It's part of the beauty. I maintain all the scripts at work, but I never tell people how to program. If it works, then that's good. I love keeping an environment with perfect directories and filenames. I don't do it so I can do sloppy programming. I love shell programming because it's quick and dirty. I also program in perl, awk, expect, python, and ruby. It's a matter of respect. I tend to err on the side of talking above people's level rather than talk down to them. Just try to think how you would respond if someone told you to use 'set -x'. I do appreciate your help. As long as I've been at it I never bothered with colors. It's just so fascinating that it could have this effect.
