I've added options. Your suggest seems to work (I learn something new everyday). However, consider foreach i (*.dat) time -a time.out foocommand $i end foreach i (*.c) time csh -c "foocommand $i" >>& time.out end One of these seems to be easier to remember for those who are not great at shell programmer. The former times the execution of foocommand while the later times the execution of csh + foocommand. If the execution time of csh is small in comparison the execution time of foocommand, then ones statistics may not be too tainted. But, what happens if csh time swamps foocommand. -- Steve finger kargl@troutmask.apl.washington.edu http://troutmask.apl.washington.edu/~clesceri/kargl.html To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
