csh cannot redirect stdout and stderr separately. You can either redirect stdout only, or redirect them both into the same file. It has *nothing* equivalent to >file1 2>file2. The usual recommendations for csh users who need to do this are either: 1) Run sh, and then run the command. 2) sh -c 'long command with >file1 2>file2'
