NAME
uptime, w - show how long system has been up and/or who is logged in and what they are doing
SYNOPSIS
uptime [-hlsuw][user]
uptime [-c][-p[pset_list ]]
w [-hlsuw][user]
w [-c][-p[pset_list ]]
DESCRIPTION
uptime prints the current time, the length of time the system has been up, the number of users logged
on to the system, and the average number of jobs in the run queue over the last 1, 5, and 15 minutes for
the active processors.
w is linked to uptime and prints the same output as
uptime -w, displaying a summary of the current
activity on the system.
Options
uptime and w recognize the following options:
-c Print the current time, the length of time the system has been up, and the number of users
logged on to the system in the first line of the output. The average number of jobs in the core
over the last 1, 5, and 15 minutes for the active processors is also printed.
When used with the
-p option, the load averages for the processor sets (psets) are calculated
on a core basis.
-h Suppress the first line and the heading line. This option should not be used with the
-u
option. This option assumes the use of the -w option to uptime.
-l Use long output. This option assumes the use of the -w option to
uptime.
-p Print the current time, the length of time the system has been up, and the number of users
logged on to the system in the first line of the output. The load averages over the last 1, 5, and
15 minutes for the processor sets (psets) given in the command line, pset_list , are displayed in
the subsequent lines. If no arguments are given, the load averages are displayed for all the
psets in the system.
If pset id of an empty pset is given in the command line, a corresponding message will be
displayed. If the kernel does not have the pset capability,
uptime gives an error. The -p
option cannot be used along with other options except -c.
-s Use the short form of output for displaying terminal information. The terminal name is abbre-
viated, and the login time and CPU times are suppressed.
-u Print only the first line describing the overall state of the system. This is the default for the
uptime command.
-w Print a summary of the current activity on the system for each user. This is the default for the
w command.
EXAMPLES
The command:
uptime
produces text resembling the following:
2:30pm up 14days, 2:39, 33 users, load average: 1.71, 1.88, 1.80
depending upon the current status of the system.
The command:
uptime -p
gives the load average of all the psets in the system. If 0, 94, 95, and 97 are existing psets in the system,
the output will look like the following:
7:59pm up 11 days, 6:25, 12 users
