LASTCOMM(1)						      General Commands Manual						       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	containing
       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 username 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  cre-
	      ated 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.
