Thanks - I didn't know time used stderr and I didn't think about that being a possibility. I have logger in there because I was considering whether to put the output in syslog, or a file in /var/log, and either way I like the formatting you get with the -i option. Now I've really confused myself. I ran it without the tee on three different systems (buntu, Mandrake, a nameless proprietary OS) and got three different answers! --- ==> time sudo echo 'hi mom' 2>&1 | logger -i -f /var/log/test.log real 0m0.018s user 0m0.000s sys 0m0.016s ==> cat /var/log/test.log --- ==> time sudo echo 'hi mom' 2>&1 | logger -i -f /var/log/test.log ==> cat /var/log/test.log --- ==> time sudo echo 'hi mom' 2>&1 | logger -i -f /var/log/test.log Password: real 0m2.835s user 0m0.004s sys 0m0.014s ==> cat /var/log/test.log hi mom --- Poking around seems to indicate that the -i option doesn't work when used in combination with the -f option, but I can't explain the differences in output past that. Jeez, I thought this would be easy! Brian -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
