ckill 1.0.1

Cleanly kills a process. Sends a SIGTERM signal, waits for it to die, and if it doesn't, SIGKILL all its subprocesses in the process tree from higher (recent) to lower (former) PID value.

Utility that allows to safely and cleanly terminate a multiprocess application that implements a shutdown, clean-up, or exit routine when a SIGTERM is received.

ckill sends a SIGTERM signal to the main process, waits for it to die, and if it doesn’t after some timeout, SIGKILL all its subprocesses in the process tree from higher (recent) to lower (former) PID value.

In this way, ckill allows the process to terminate correctly, but if it malfunctions when terminating, or if it takes too much time (determined by the user) all its subprocesses are killed and then the main process itself, leaving no zombie processes behind.
