- WHO(1) Minix Programmer's Manual WHO(1)
- NAME
- who - print list of currently logged in users
- SYNOPSIS
- who [file]
- EXAMPLES
- who # Print user names, terminals and times
- DESCRIPTION
- Who prints a list of currently logged in users. For each one, the user
- name, terminal, and login time is printed. This program gets its
- information from the file /etc/utmp, which is updated by init and login.
- If the file does not exist, neither of these will create it, and who will
- not work. Note that if you decide to create an empty /usr/adm/wtmp to
- enable the login accounting, it will grow forever and eventually fill up
- your disk unless you manually truncate it from time to time. If an
- optional file name is provided, the logins in that file will be printed.
- SEE ALSO
- utmp(5).
