How can I kill a process by name instead of PID, on Linux? [duplicate]
You can kill processes by name with killall <name>
killall sends a signal to all processes running any of the specified commands. If no signal name is specified, SIGTERM is sent.
Signals can be specified either by name (e.g. -HUP or -SIGHUP ) or by number (e.g. -1) or by option -s.
If the command name is not regular expression (option -r) and contains a slash (/), processes executing that particular file will be selected for killing, independent of their name.
But if you don't see the process with ps aux, you probably won't have the right to kill it ...
