37 .Nd who present users are and what they are doing
47 utility prints a summary of the current activity on the system,
48 including what each user is doing.
49 The first line displays the current time of day, how long the system has
50 been running, the number of users logged into the system, and the load
52 The load average numbers give the number of jobs in the run queue averaged
53 over 1, 5, and 15 minutes.
55 The fields output are the user's login name, the name of the terminal the
56 user is on, the host from which the user is logged in, the time the user
57 logged on, the time since the user last typed anything,
58 and the name and arguments of the current process.
60 The options are as follows:
65 Output is sorted by idle time.
67 Extract values associated with the name list from the specified
68 core instead of the default
71 Extract the name list from the specified system instead of the
75 Show network addresses as numbers (normally
77 interprets addresses and attempts to display them symbolically).
79 Show wide output without truncating any fields.
84 name is specified, the output is restricted to that user.

104 The current algorithm is ``the highest numbered process on the terminal
105 that is not ignoring interrupts, or, if there is none, the highest numbered
106 process on the terminal''.
107 This fails, for example, in critical sections of programs like the shell
108 and editor, or when faulty programs running in the background fork and fail
109 to ignore interrupts.
110 (In cases where no process can be found,
115 Background processes are not shown, even though they account for
116 much of the load on the system.
118 Sometimes processes, typically those in the background, are printed with
119 null or garbaged arguments.
120 In these cases, the name of the command is printed in parentheses.
124 utility does not know about the new conventions for detection of background
126 It will sometimes find a background job instead of the right one.
