How to Kill a Mac process using PID - QuickLookUIService

Question

OSX has a stupid bug where the " QuickLookUIService " needs to be restarted to work properly.
I want to create a script that will kill it automatically when the script is launched, but I can only achieve that by killing the Process ID .

When I use GREP to get the PID of QuickLookUIService I get 3 results

Getting the Wrong PID screenshot

and therefore I can never get the correct PID number in order to kill it.

I tried the following:

killall QuickLookUIService

ps aux | grep 'QuickLookUIService' | head -1 | cut -d " " -f 2 | xargs kill

kill $(ps aux | grep 'QuickLookUIService' | awk '{print $2}')

ps aux | grep QuickLookUIService | awk '{print $2}' | xargs kill

ps -ef  | grep -e QuickLookUIService | awk '{print $2}' | xargs sudo kill

All of which gave me the wrong PID s

Any Help would be greatly Appriciated

Answer 1

killall QuickLookUIService

That should work. The others are not working because by the time the list is generated a new process has been created.
