M> kill -9 `ps ax | grep backup | grep -v grep | awk '{print $1}'`
I've typed "ps ax | grep something | grep -v grep" often enough to
automate it. The "psax" script below accepts an optional egrep-style
regex and displays only the matching processes.
You can make your life easier by using process groups more often.
For example, in the comments below there are four separate httpd
processes in the same process group. If I wanted to kill them all,
I could send HUP to PGID 198 instead of using four kill commands.
There's a perl version of "kill" included in Perl power tools. I made
some minor changes to use process groups instead:
