Syntax

w [  -h ] [  -u ] [  -w ] [  -l |  -s  [ -X ] [ -@ [ WPAR ] ][ User ]

Description

The w command prints a summary of the current activity on the system. The summary includes the following:

Item Description
WPAR Workload partition name.
User Who is logged on.
tty Name of the tty the user is on.
login@ Time of day the user logged on.
idle Number of minutes since a program last attempted to read from the terminal.
Note: The idle time is taken from the global terminal when you log into wpar using the clogin command.
JCPU System unit time used by all processes and their children on that terminal.
PCPU System unit time used by the currently active process.
What Name and arguments of the current process.

The heading line of the summary shows the current time of day, how long the system has been up, the number of users logged into the system, and the load average. The load average is the number of runnable processes over the preceding 1-, 5-, 15-minute intervals.

The following examples show the different formats used for the login time field:

Item Description
10:25am The user logged in within the last 24 hours.
Tue10am The user logged in between 24 hours and 7 days.
12Mar91 The user logged in more than 7 days ago.

If a user name is specified with the User parameter, the output is restricted to that user.

Flags

Item Description
-@ Prints the System activity tagged with a workload partition name:
  • providing the -@ option without a WPAR name indicates the global environment in addition to all WPARs active in the system, and the heading line indicates values for the global environment only
  • providing the -@ option with a WPAR name indicates the activity, and the heading line indicates values for only that WPAR
  • providing -@ Global indicates the activity, and the heading line indicates values for the global environment only.
Note: Not providing the -@ option indicates that the current WPAR or global environment, wherever the w command is running.
-h Suppresses the heading.
-l Prints the summary in long form. This is the default.
-s Prints the summary in short form. In the short form, the tty is abbreviated, and the login time, system unit time, and command arguments are omitted.
-u Prints the time of day, amount of time since last system startup, number of users logged on, and number of processes running. This is the default. Specifying the -u flag without specifying the -w or -h flag is equivalent to the uptime command.
-w The equivalent of specifying the -u and -l flags, which is the default.
-X Prints all available characters of each user name instead of truncating to the first 8 characters. The user name is also moved to the last column of the output.
