pslist - 1.4.0-6 main

pslist is a simple utility to list the process IDs (PIDs) of a process and
all its children, and its children's children, and so on. If invoked with
a command name which ends in 'kill', it sends a signal to a selected group
of processes. If invoked with a command name which ends in 'renice',
it sets the nice level of the selected group of processes.
