Kill all processes related to an application
If you want to do it by name:
If you want to kill a specific process, e.g. the first Firefox instance:
and if the process doesn't want to go, you can use:
kill -KILL 38261
There should be no way for a program to keep the OS from terminating it RIGHT NOW.
Update: To see a list of all available process names for the
killall command, you can use:
ps -axco command | sort | uniq
You could do
kill `pgrep Xvfb` `pgrep Firefox`
You can add -f to search the entire command, in case it doesn't find it without the -f.
pgrep -f Firefox
There is also pkill which takes the same input as pgrep
pkill Xvfb; pkill -f Firefox;
