Grep is grepping itself

I sometimes need to stop an application with the kill command, due to it being frozen, or simply being buggy. The command to kill requires me to know the PID of the process.

ps aux | grep name-of-the-application

There will be at least 2 outputs: One with the application we want to kill, and the other one with the actual grep process we are running to find the PID in the first place:

pre      18775  1.2  0.0  12524  1972 pts/3    S    20:17   0:00 
pre      19137  0.0  0.0   9136  1068 pts/3    S+   20:17   0:00 grep --color=auto application-name

In order exclude grep from the output result I have found the following command

ps aux | grep application name | grep -v grep

Compliment of this answer
