From csh manual page, I got:
Diagnostic output may be directed through a pipe with the
standard output. Simply use the form `|&' rather than
just `|'.
The shell cannot presently redirect diagnostic output
without also redirecting standard output, but `(command >
output-file) >& error-file' is often an acceptable
workaround. Either output-file or error-file may be
`/dev/tty' to send output to the terminal.
it seems I can not separate stderr from stdout.
