Linux w command
The Linux w command is used to display information about users currently logged into the system.
Running this command shows which users are currently logged into the system and the programs they are executing.
Executing the w command alone displays all users. You can also specify a username to show information about a particular user only.
Syntax
w [-fhlsuV][用户名称]
Parameter Description:
- -f Turn on or off displaying where users logged into the system from.
- -h Do not display the title information row of each column.
- -l Use the detailed format list; this is the default value.
- -s Use the concise format list, without displaying user login time, terminal session jobs, and CPU time consumed by programs.
- -u Ignore the name of the executing program and information about the CPU time consumed by that program.
- -V Display version information.
