Terminate a process and force kill only if needed

caution rootProcessesdebian, ubuntu

Caution: This command changes the system. Understand what it does before you run it.

Adjust the values, the command updates live
root@server
kill 1234; sleep 5; kill -0 1234 2>/dev/null && kill -9 1234

Sends the normal termination signal first, so the process can clean up, close files and finish transactions. After five seconds, kill -0 checks whether it still exists, and only then follows kill -9, which terminates immediately without cleanup. Root is only needed for other users’ processes.

Note: Check the PID beforehand with ps -fp <PID>. Never stop database servers like MariaDB with kill -9, use systemctl stop instead.
