40 .Nd "display who is logged in and what they are doing"
50 utility prints a summary of the current activity on the system,
51 including what each user is doing.
52 The first line displays the current time of day, how long the system has
53 been running, the number of users logged into the system, and the load
55 The load average numbers give the number of jobs in the run queue averaged
56 over 1, 5 and 15 minutes.
58 The fields output are the user's login name, the name of the terminal the
59 user is on, the host from which the user is logged in, the time the user
60 logged on, the time since the user last typed anything,
61 and the name and arguments of the current process.
63 The options are as follows:
64 .Bl -tag -width indent
66 dumps out the entire process list on a per controlling
67 tty basis, instead of just the top level process.
71 Output is sorted by idle time.
73 Extract values associated with the name list from the specified
74 core instead of the default
77 Extract the name list from the specified system instead of the
79 .Pa /boot/kernel/kernel .
81 Do not attempt to resolve network addresses (normally
83 interprets addresses and attempts to display them as names).
88 names are specified, the output is restricted to those users.
90 .Bl -tag -width ".Pa /var/run/utmp" -compact
92 list of users on the system
101 flags are no longer supported.
116 The current algorithm is
118 the highest numbered process on the terminal
119 that is not ignoring interrupts, or, if there is none, the highest numbered
120 process on the terminal
122 This fails, for example, in critical sections of programs like the shell
123 and editor, or when faulty programs running in the background fork and fail
124 to ignore interrupts.
125 (In cases where no process can be found,
132 time is only an estimate, in particular, if someone leaves a background
133 process running after logging out, the person currently on that terminal is
137 Background processes are not shown, even though they account for
138 much of the load on the system.
140 Sometimes processes, typically those in the background, are printed with
141 null or garbaged arguments.
142 In these cases, the name of the command is printed in parentheses.
146 utility does not know about the new conventions for detection of background
148 It will sometimes find a background job instead of the right one.
