Hmm, well in this case you are redirecting the strace output to file, so the grep command has nothing to work from from the pipe. ! Either > strace -o gm.txt gmfsk > grep xxx gm.txt or as I said in a previous post > strace gmfsk 2>&1 | grep xxx here, the 2>&1 redirects the stderr to stdout, so it is then seen by the pipe (|) and grep commands Chris
