How to check if a user is active or not in Linux
Team W: The w command is used to show who is logged in and what they are doing. w displays information about the users currently on the computer and their processes. The header shows, in this order, the current time, how long the system has been running, the number of users currently logged on, and system load averages for the last 1, 5, and 15 minutes.
The following entries are displayed for each user:
- login
- terminal name
- remote host
- login time
- downtime
- JCPU and PKPU
- current process command line
Who is in command: “who” prints information about users who are currently logged in. If the command does not specify a non-option argument, “who” prints the following information for each user currently logged on:
- login
- end line
- login time
- remote hostname or X mapping
If you want to see the date and time the system was last booted, run the who command with the “–boot” argument.
When you run the who command with the “-q” or “-count” argument, it only displays logins and the number of logged-in users. This will override all other settings.
When you execute the who command with the -u option, it will show the idle time. After the login time, print the number of hours and minutes the user has been idle. ‘.’ means that the user was active at the last minute. “old” means the user has been inactive for more than 24 hours.
