this was a very valuable thread -- i'm very glad i asked the question and even more glad people riffed with the theme. but the actual answer is completely unacceptable. i can't believe that this is so complicated under bash! i really wish that the bash developers would so something like: strace foo 2| grep bar i see this as a bash deficiency. :( but it _was_ a great lesson! pete _______________________________________________ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
