Hi Peter, Thanks for the quick reaction. Actually my blunder was putting a $ sign before list and fullist (another legacy from a previous attempt, but a harmful one, for a change). As to your remarks: 1-ls formats the output in severeal columns only when the output goes to a terminal, which is not the case in this script 2-I do not remember starting any number with a zero, but,I'll have another look. Your remark is, of course, valid. Cheers, Avraham
