ls file1 file2 2>&1 >stdout-file | grep -v pattern >stderr-file
You need to do the 2>&1 BEFORE redirecting stdout (even if you didn't want
to redirect stdout, you will have to do so)

well; yes.
maybe I should explain better what I want.
I run filemon (or netpmon).
It prints things like "reporting started" etc. to stderr.
stderr is redirected to /some/file
I dont want these "reporting started" etc. things every time it runs.
So I want to grep it out.
"Real" (other) errors should however get to the errorfile that stderr is
redirected to.

Hello,
can I grep stderr of a command without a 2>&1 ?
F.e. if file1 exists and file2 doesnt,
ls file1 file2 |"errgrep" file2
should give file1 on stdout and nothing on stderr.
Regards,
Holger
