OK, then, how about tar(1)'s -T (or -I, or --files-from) option? :) Something like.. find -s "$I" \! -type d > files.lst tar -czf "$I.tgz" -T files.lst Or, even a bit simpler, using the standard Unix convention that '-' as a file name means the standard input (or output, as appropriate): find -s "$I" \! -type d | tar -czf "$I.tgz" -T - Would that work for you?
