Trick to avoid the form: grep process | grep - v grep Show Sample Output
Get the PID of a process by name Show Sample Output
preferred way to query ps for a specific process name (not supported with all flavors of ps, but will work on just about any linux afaik) Show Sample Output
faster ;) but your idea is really cool
This does the same thing as many of the 'grep' based alternatives but allows a more finite control over the output. For example if you only wanted the process ID you could change the command:
ps -ef | awk '/mingetty/ && !/awk/ {print $2}'
If you wanted to kill the returned PID's:
ps -ef | awk '/mingetty/ && !/awk/ {print $2}' | xargs -i kill {}
Show Sample Output
Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
