Internal Program Version: psmisc  23.7

The psmisc package contains utilities for managing processes on your
system: pstree, killall and fuser.  The pstree command displays a tree
structure of all of the running processes on your system.  The killall
command sends a specified signal (SIGTERM if nothing is specified) to
processes identified by name.  The fuser command identifies the PIDs of
processes that are using specified files or filesystems.
