A quick short-cut for the last part:
ps -A | grep -e "[ /]python2.1\>" >/dev/null 2>&1
"1" (stdout) is used by default, and then 2>&1 takes "2" (stderr) and
sends (>) it to the same location (&) as "1".

Hi all,
i would like to write a simple shell script that checks for the existence of a certain
programme, in this case python2.1. if the
programme is active, do nothing, if not, start it.
i did think of doing a ps -A |grep python2.1, but then i have no idea how to
intergrate that in the shell
