A notation is important for what it leaves out.

One of my favorites is:

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

The above will find and kill a process that matches search string.

Very nice, but you should eliminate the process that contain grep:
kill -9 $(ps -ef|grep search_string|grep -v grep|awk -F " " '{ print $2 }')

You can do it without grep too:

kill -9 $(ps -ef | awk '/search pattern/ { print $2 }')

And to avoid errors if nothing is found:

ps -ef | awk '/search pattern/ { print $2 }' | xargs -r kill -9

instead of "grep -v grep" you can also use "grep [s]earch_string" so the full line would look like:

kill -9 $(ps -ef | grep [s]earch_string | awk -F " " '{ print $2 }')
