PROGRAM:
NAME
pslist — control processes and their descendants
SYNOPSIS
pslist [pid/name...]
pslist -h | --help
pslist -v | --version
rkill [-SIG] pid/name...
rrenice [+/-]pri pid/name...
DESCRIPTION
The pslist 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, pslist displays a list of the whole process tree. For each process
specified on the command line, pslist 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.
RETURN VALUES
The pslist utility exits 0 on success, and >0 if an error occurs.
Use rrenice online using onworks.net services
