I used strace -o gm.txt gmfsk | grep xxxx but the grep did not work
but
I got the whole mess saved in gm.txt now. But Nigel had a better idea
and his works...
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
