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

(...continues until killed)
Is this the way that it's supposed to work, or is this an
its-not-a-bug-its-a-feature?
