Booting and Shutting Down Oracle^® Solaris 11.3 Systems

How to Determine Who Is Logged in to the System

For Oracle Solaris systems that are used as multiuser timesharing systems, you might need to determine if any users are logged into the system before shutting it down. Use the following procedure in these instances.

• To determine who is logged in to a system, use the who command, as follows:

  $ who
  holly       console      May  7 07:30
  kryten      pts/0        May  7 07:35   (starlite) 
  lister      pts/1        May  7 07:40   (bluemidget)

  • Data in the first column identifies the user name of the logged-in user.

  • Data in the second column identifies the terminal line of the logged-in user.

  • Data in the third column identifies the date and time that the user logged in.

  • Data in the fourth column, if present, identifies the host name if the user is logged in from a remote system.
