I can't help but to post something a little more explicit. Sorry. echo <(cat ~/.bash_history) /proc/self/fd/63 Therefore you are saying effectively this: while read f; do echo $f; done $FILENAME That obviously won't work. You need a redirection operator there. while read f; do echo $f; done < $FILENAME Seeing that you can see that this is the right syntax. while read f; do echo $f; done < <(cat ~/.bash_history) Bob _______________________________________________ Bug-bash mailing list Bug-bash@gnu.org http://lists.gnu.org/mailman/listinfo/bug-bash
