Hello! What is going on here? ~$ ps -f | grep $$ peda 2316 1 con 20:21:51 /usr/bin/bash peda 3180 2316 con 21:51:47 /usr/bin/ps peda 3164 2316 con 21:51:47 /usr/bin/grep [I use bash, if that matters] ~$ tail -f frame.log | grep Antenna 2005-05-11,21:51:07: Antenna DAC 0 2005-05-11,21:51:17: Antenna DAC 0 2005-05-11,21:51:26: Antenna DAC 0 2005-05-11,21:51:36: Antenna DAC 0 2005-05-11,21:51:46: Antenna DAC 0 2005-05-11,21:52:06: Antenna DAC 0 [Fine, that works, I get bored and press ^C] ~$ tail frame.log | grep Antenna | cat 2005-05-11,21:51:17: Antenna DAC 0 2005-05-11,21:51:26: Antenna DAC 0 2005-05-11,21:51:36: Antenna DAC 0 2005-05-11,21:51:46: Antenna DAC 0 2005-05-11,21:52:06: Antenna DAC 0 [Fine, that works...] ~$ tail -f frame.log | grep Antenna | cat [No output!? I'm puzzled and press ^C] Every other line in frame.log is an "Antenna"- line, so I really think there should be output from the last command as well. (For the real task I'm doing I want to do more than 'cat' at the end of the pipe, this is just a trimmed down example.) Can anyone please provide any hints? Cheers, Peter
