LASTCOMM(1)									      LASTCOMM(1)

NAME
       lastcomm -  print out information about previously executed commands.

SYNOPSIS
       lastcomm
	      [ command-name ...  ]
	      [ user-name ...  ]
	      [ terminal-name ...  ]
	      [ OPTION ... ]

DESCRIPTION
       lastcomm  prints  out information about previously executed commands.  If no arguments are
       specified, lastcomm will print info about all of the commands in acct (the  record  file).
       If called with one or more of command-name, user-name, or terminal-name, only records con-
       taining those items will be displayed.  For example, to find out which users used  command
       `a.out' and which users were logged into `tty0', type:
					  lastcomm a.out tty0

       This  will  print  any  entry  for  which `a.out' or `tty0' matches in any of the record's
       fields (command, name, or terminal).  If you want to find only items that match	*all*  of
       the  arguments on the command line, you must use the '-strict-match' option.  For example,
       to list all of the executions of command a.out by user root on terminal tty0, type:
		     lastcomm --strict-match --command a.out --user root --tty tty0

       The order of the arguments is not important.

       For each entry the following information is printed:
	  + command name of the process
	  + flags, as recorded by the system accounting routines:
	       S -- command executed by super-user
	       F -- command executed after a fork but without a following exec
	       C -- command run in PDP-11 compatibility mode (VAX only)
	       D -- command terminated with the generation of a core file
	       X -- command was terminated with the signal SIGTERM
	  + the name of the user who ran the process
	  + time the process started

OPTIONS
       --strict-match
	      Print only entries that match *all* of the arguments on the command line.
       --print-controls
	      Print control characters.
       --user name
	      List records for user with name.	This is useful if you're trying to match a  user-
	      name that happens to be the same as a command (e.g., ed ).
       --command name
	      List records for command name.
       --tty name
	      List records for tty name.
       --forwards
	      Read file forwards instead of backwards. This avoids trying to seek on the file and
	      can be used to read from a pipe. This must be specified prior to any -f arguments.
       -f filename, --file filename
	      Read from the file filename instead of acct.  A filename	of  "-"  will  result  in
	      reading  from  stdin.  This  must either be the first -f option, or --forwards must
	      precede all -f options.
       --ahz hz
	      Use this flag to tell the program what AHZ should be (in hertz).	 This  option  is
	      useful  if you are trying to view an acct file created on another machine which has
	      the same byte order and file format as your current machine, but	has  a	different
	      value for AHZ.
       -p, --show-paging
	      Print paging statistics
       --debug
	      Print verbose internal information.
       -V, --version
	      Print the version number of lastcomm.
       -h, --help
	      Prints  the  usage  string and default locations of system files to standard output
	      and exits.

FILES
       acct
	      The system wide process accounting file. See acct(5) (or pacct(5)) for further  de-
	      tails.  /var/log/account
		     This  directory  contains	pacct  files which contain the binary process ac-
		     counting data as written by the kernel.
