I just read the following command:
taskkill /f /im something.exe
I read that /f forces the task to close, but what does /im do?
It tells taskkill that the next parameter something.exe is an image name, a.k.a executable name
C:\>taskkill /?
TASKKILL [/S system [/U username [/P [password]]]]
{ [/FI filter] [/PID processid | /IM imagename] } [/T] [/F]
