NAME
	  ac - Outputs connect-session records

     SYNOPSIS
	  ac [-dp] [-w filename] [user(s) ...]


     FLAGS
	  -d	    Outputs the	total connect time for each midnight-
		    to-midnight	period for which a wtmp	file exists.
		    When user(s) is specified, this flag limits	the
		    output to the login	names specified	by any user(s)
		    parameter(s).

	  -p	    Outputs the	connect	time total by individual login
		    name of the	user specified with the	-p flag	and
		    the	user(s)	parameter.  Omission of	this flag only
		    permits a total for	the midnight-to-midnight time
		    period for all logged in users to be produced.

	  -w  filename
		    Specifies a	wtmp file other	than the /var/adm/wtmp
		    file.  The wtmp file you access for	data may have
		    been created automatically by some shell script
		    administration command; for	example, runacct, or
		    manually by	the system administrator when the ori-
		    ginal /var/adm/wtmp	file becomes too large.


     DESCRIPTION
	  The ac command prints	to the default output device the total
	  connect time in hours	to the nearest hundredth for all
	  users, or the	connect	time for any user(s) specified with
	  the -p flag. It also prints the names	of users specified by
	  the user(s) parameter	who have logged	in during the life of
	  the current /var/adm/wtmp file.

	  Connect-time records are written by the init and the login
	  programs and are collected in	the /var/adm/wtmp file,	when
	  such a file exists. When a /var/adm/wtmp file	does not
	  exist, no connect-time accounting records are	written; con-
	  sequently, when connect-time records are wanted, the system
	  administrator	should create a	/var/adm/wtmp file that	has an
	  initial record length	of 0 (zero). Records in	wtmp files
	  (there may be	more than one such file) should	be processed
	  periodically to keep the files from becoming too large.

	  When you use the runacct command in a	shell script, addi-
	  tional wtmp files can	be automatically created whenever the
	  current wtmp file becomes too	large. You can output the con-
	  tents	of any of these	other files when you specify the -w
	  flag and the desired wtmp filename.
	  The ac command is run	independently with respect to any
	  accounting shell procedure created or	run by any of the
	  acct/* shell procedures or runacct commands.

     EXAMPLES
	   1.  To obtain an output of the total	connect	time for all
	       users who have logged in	during the life	of the current
	       wtmp data file, enter:

	       /usr/sbin/ac


	   2.  To obtain an output of the total	connect	time for
	       grossman	and mcwhinney as recorded in the default wtmp
	       data file, enter:

	       /usr/sbin/ac  grossman  mcwhinney


	   3.  To obtain an output of the connect time subtotals for
	       grossman	and mcwhinney as recorded in the default wtmp
	       data file, enter:

	       /usr/sbin/ac -p	grossman  mcwhinney


     FILES
	  /usr/sbin/ac
		    Specifies the command path.

	  /var/adm/wtmp
		    The	active data file for the collection of
		    connect-time records
