ac(8)
NAME
  ac - Outputs connect-session records

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

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

  -p  Outputs the connect time total by individual login name of the user
      specified with the -p option and the user(s) operand. Omission of this
      option permits a total only 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 original /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 option. It also prints the names of users
  specified by the user(s) operand 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; consequently, 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, additional wtmp files
  can be automatically created whenever the current wtmp file becomes too
  large. You can output the contents of any of these other files when you
  specify the -w option 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
      Is the active data file for the collection of connect-time records.
