find and kill a zombie process

You cannot kill zombies, as they are already dead. But if you have too many zombies then kill parent process or restart service.

You can kill zombie process using PID obtained from the above command. For example kill zombie proces having PID 4104:

# kill -9 4104

Please note that kill -9 does not guarantee to kill a zombie process.

Display any tcp connections to apache

Sometimes apache will get stuck in an established state where you can't get a list of the connecting IP's from mod_status... not a good thing when you need to ban an abusive ip.

find and kill a pid for APP

Probably posted previously, I use this all the time to find and kill a process for "APP". Simply replace "APP" with the name of the process you're looking to kill.

pattern match in awk - no grep

Rather than chain a string of greps together and pipe them to awk, use awk to do all the work. In the above example, a string would be output to stdout if it matched pattern1 AND pattern2, but NOT pattern3.

kill all foo process

Kill all processes with foo in them. Similar to pkill but more complete and also works when there is no pkill command.

Works on almost every Linux/Unix platform I have tried.
