Internal Program Version: whowatch 1.8.6-dae08e4 (The man files)

whowatch is an console, interactive users and process monitoring tool. It
displays information about the users currently logged on to the machine,
in real-time. Besides standard information (login name, tty, host,
user's process), the type of the connection (ie. telnet or ssh) is shown.
Display of users command line can be switch to tty idle time. Certain user
can be selected and his processes tree may be viewed as well as tree of all
system processes. Tree may be displayed with additional column that shows
owner of each process. In the process tree mode SIGINT, SIGHUP, SIGTERM and
SIGKILL signals can be sent to the selected process. Killing processes is
just as simple and fun as deleting lines on the screen.
