One-liner which kills a Unix process given its name

kill_portal.sh

# Kill a process, given part of its name
#
# How I'm doing it:-
# 
# 1. Get a list of all processes
# 2. Grep for any process where "portal" is part of the 
#    command line used to launch it
# 3. I will get 2 processes: 1 of them is what I'm searching for &
#    the other is just this grep command I'm running. I remove it by
#    removing anything with "grep" in its command line
# 4. Get the 2nd column (the process ID)
# 5. kill this process

kill -9 `ps -ef | grep portal | grep -v grep | awk '{print $2}'`

Why not killall ?

killall portal

I didn't know about killall before, but it's easier of course. I think that my solution works on other Unix systems as well.
