tail -f /var/log/messages | grep "foo" above works fine and i get lines with "foo" that gets into /var/log/messages.
tail -f /var/log/messages | grep "foo" | grep "bar" doesn't produce any output although there are lines with "foo" and "bar" tail -f /var/log/messages | grep "foo" | grep "foo" This doesn't produce any output either !!! After breaking the tail command i test wether there were lines that should have been displayed. Then i see that there were valid lines cat /var/log/messages | grep "foo" | grep "bar" I assume it is a bug but i'm not sure I use Suse linux 6.3 and have installed tail (GNU textutils) 2.0 grep (GNU grep) 2.4.2 Frits Verlijsdonk system administrator Smeva BV, The Netherlands _______________________________________________ Bug-textutils mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-textutils
