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 even-
       tually 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.

Name
       ac - login accounting

Syntax
       /etc/ac [ -w wtmp ] [ -p ] [ -d ] [ people ] ...

Description
       The  command  produces a printout giving connect time for each user who has logged in during the life of the current wtmp file.	A total is
       also produced.

       The accounting file is maintained by and Neither of these programs creates the file, so if it does not exist no connect-time accounting	is
       done.   To  start  accounting,  it should be created with length 0.  On the other hand if the file is left undisturbed it will grow without
       bound, so periodically any information desired should be collected and the file truncated.

Options
       -w     Specifies an alternate wtmp file.

       -p     Prints individual totals; without this option, only totals are printed.

       -d     Causes a printout for each midnight to midnight period.  Any people will limit the printout to only the specified login  names.	If
	      no wtmp file is given, is used.
