W (1) | General commands | Unix Manual Pages | :man▋
w - "display who is logged in and what they are doing"
w [-dhin] [-M core] [-N system] [user ...]
The w utility prints a summary of the current activity on the system, including what each user is doing. The first line displays the current time of day, how long the system has been running, the number of users logged into the system, and the load averages. The load average numbers give the number of jobs in the run queue averaged over 1, 5 and 15 minutes.
The fields output are the users login name, the name of the terminal the user is on, the host from which the user is logged in, the time the user logged on, the time since the user last typed anything, and the name and arguments of the current process.
The options are as follows:
|-d || dumps out the entire process list on a per controlling tty basis, instead of just the top level process. |
|-h || Suppress the heading. |
|-i || Output is sorted by idle time. |
|-M || Extract values associated with the name list from the specified core instead of the default "/dev/kmem". |
|-N || Extract the name list from the specified system instead of the default "/boot/kernel/kernel". |
|-n || Do not attempt to resolve network addresses (normally w interprets addresses and attempts to display them as names). |
If one or more user names are specified, the output is restricted to those users.
| /var/run/utmp |
| || list of users on the system |
The -f , -l , -s , and -w flags are no longer supported.
