DESCRIPTION
The utility examines the list of current processes to find a specified process and all its descendants. A process may be specified either by name or by process ID. If no arguments are given, displays a list of the whole process tree. For each process specified on the command line, outputs a line containing the process ID, the command name, and the PIDs of all the descendants (and their descendants, etc.).When invoked as rkill this utility does not display information about the processes, but sends them all a signal instead. If not specified on the command line, a terminate (SIGTERM) signal is sent.
When invoked as rrenice this utility does not display information about the processes, but attempts to set their nice value instead.
