lastcomm(1)							   User Commands						       lastcomm(1)

NAME

       lastcomm - display the last commands executed, in reverse order

SYNOPSIS

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

DESCRIPTION

       The  lastcomm command gives information on previously executed commands. lastcomm with no arguments displays information about all the com-
       mands recorded during the current accounting 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 appro-
       priate 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 acct(2)).

       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.

OPTIONS

       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 processing accounting is inactive, no output will be
		  produced.
