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.
