Does su have some kind of a built-in nohup option? If I su to root and execute a command or shell script and then disconnect (ie, quit the terminal software I'm running, which in my case is an ssh session) whatever I was last running su'd as root continues to run until I manually kill it. Processes that generate lots of output also seem to generate lots of CPU usage running in this "background" mode. You can see this demonstrated by doing: $ su [-l] # while true; do date >> testing.txt; sleep 2; done (disconnect session) (on some other session on the same box) $ tail -f testing.txt Thu Jul 20 14:47:00 CDT 2000 Thu Jul 20 14:47:02 CDT 2000 Thu Jul 20 14:47:04 CDT 2000 (...continues until killed) Is this the way that it's supposed to work, or is this an its-not-a-bug-its-a-feature? -- swb@grasslake.net Hard work often pays off after time, but laziness always pays off now.
