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.
-2ps -ef | grep APP | awk '/grep/!{print$2}' | xargs -i kill {} -
The description of how the one-liner works is here at my blog: http://jugad2.blogspot.com/2008/09/unix-one-liner-to-kill-hanging-firefox.html Show Sample Output
-2kill -HUP ` ps -aef | grep -i firefox | sort -k 2 -r | sed 1d | awk ' { print $2 } ' ` -

The '[r]' is to avoid grep from grepping itself. (interchange 'r' by the appropriate letter) Here is an example that I use a lot (as root or halt will not work):
while (ps -ef | grep [w]get); do sleep 10; done; sleep 60; haltI add the 'sleep 60' command just in case something went wrong; so that I have time to cancel. Very useful if you are going to bed while downloading something and do not want your computer running all night.-2while (ps -ef | grep [r]unning_program_name); do sleep 10; done; command_to_execute -
-2ps auxwww | grep outofcontrolprocess | awk '{print $2}' | xargs kill -9
-
-2ps -a |grep cat |wc -l
-
-2ps -cx cat

I know you can use pidof but with this you can know the specific PID with his command arguments (useful if you're running various proccess with same application)
-2pss() { ps -eo pid,args | sed '/'"$1"'/!d;/sed/d' ; } -
-2who;ps aux|grep ssh
-
-2ps -eo pid,args | grep -v grep | grep catalina | awk '{print $1}'

defunct processes (zombies) usually have to be killed by killing their parent processes. this command retrieves such zombies and their immediate parents and kills all of the matching processes.
-2ps afx | grep defunct -B 1 | grep -Eo "[0-9]{3,}" | xargs kill -9 -
-2renice -20 -g 2874 (2784 found with ps -Aj)

Function that searchs for process by its name: * Shows the Header for reference * Hides the process 'grep' from the list * Case sensitive The typical problem with using "ps | grep" is that the grep process shows up the in the output. The usual solution is to search for "[p]attern" instead of "pattern". This function turns the parameter into just such a [p]attern.
${1:0:1} is the first character of $1.${1:1} is characters 2-end of $1Show Sample Output-2psg(){ ps aux | grep -E "[${1:0:1}]${1:1}|^USER"; } -
