WHOWATCH(1) General Commands Manual WHOWATCH(1) NAME whowatch - watch logged in users and processes in real time DESCRIPTION Whowatch is an interactive ncurses who-like utility that displays in- formation about the users currently logged on to the machine, in real- time. Besides standard informations (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 SIG- INT and SIGKILL signals can be sent to the selected process. Killing processes is just as simple and fun as deleting lines on the screen. Whowatch has no command line options or configuration file. All actions are performed in real time by pressing following keys: Users list mode: 'up' 'down' cursor movement 'i' toggle between user command line and idle time 'c' full command line on/off. Disabling full command line can save CPU time. It can give you also some additional information about process executable. 'enter' view selected user's processes tree. 't' all system processes (init tree) Tree mode: 'up' 'down' cursor movement 'enter' go back to users list 'o' show processes owners 'c' full command line on/off. Disabling full command line can save CPU time. It can give you also some additional information about process executable. 'Ctrl-I' send INT signal to selected process 'Ctrl-K' send KILL signal to selected process FILES Program reads /var/log/wtmp, /var/run/utmp. Under Linux program also reads files from /proc directory. Without read access to these files whowatch funcionality will be limited or program will not even start. SEE ALSO finger(1) ps(1), pstree(1), top(1), w(1), BUGS Because lack of ut_pid in utmp and wtmp structures in *BSD systems, program tries to obtain pid of a login shell by analizing processes controlling terminal and processes names. Under some conditions it may lead to incorrect results ie. there will be incorrect processes tree associated with user's session.
