lastcomm(1)				  User Commands 			      lastcomm(1)

       lastcomm - display the last commands executed, in reverse order

       lastcomm [-f file] [-x] [command-name] ... [user-name] ...
	    [terminal-name] ...

       The  lastcomm  command gives information on previously executed commands. lastcomm with no
       arguments displays information about all the commands recorded during the current account-
       ing  file's  lifetime. If called with arguments, lastcomm only displays accounting entries
       with a matching command-name, user-name, or terminal-name. If extended process  accounting
       is active (see acctadm(1M)) and is recording the appropriate data items, lastcomm attempts
       to take data from the current  extended	process  accounting  file.  If	standard  process
       accounting  is  active, lastcomm takes data from the current standard accounting file (see

       If terminal-name is `- -', there was no controlling TTY for the process. The  process  was
       probably  executed  during boot time. If  terminal-name is `??', the controlling TTY could
       not be decoded into a printable name.

       For each process entry, lastcomm displays the following items of information:

	   o	  The command name under which the process was called.

	   o	  One or more flags indicating special information about the process.  The  flags
		  have the following meanings:

		  F    The process performed a fork but not an exec.

		  S    The process ran as a set-user-id program.

	   o	  The name of the user who ran the process.

	   o	  The terminal which the user was logged in on at the time (if applicable).

	   o	  The amount of CPU time used by the process (in seconds).

	   o	  The date and time the process exited.

       The following options are supported:

       -f file	  Uses	file  as  the  source  of accounting data. file may be either an extended
		  process accounting file or a standard process accounting file.

       -x	  Uses the currently active extended process accounting file.  If  extended  pro-
		  cessing accounting is inactive, no output will be produced.

       Example 1 Listing executions of named commands

       The command

	 example% lastcomm a.out root term/01

       produces  a listing of all the executions of commands named a.out by user root while using
       the terminal term/01.

       Example 2 Listing all user commands

       The command

	 example% lastcomm root

       produces a listing of all the commands executed by user root.

       /var/adm/pacct	       standard accounting file

       /var/adm/exacct/proc    extended accounting file
