LASTCOMM(1)						    BSD General Commands Manual 					       LASTCOMM(1)

NAME

     lastcomm -- show last commands executed in reverse order

SYNOPSIS

     lastcomm [-w] [-f file] [command ...] [user ...] [terminal ...]

DESCRIPTION

     lastcomm gives information on previously executed commands.  With no arguments, lastcomm prints information about all the commands recorded
     during the current accounting file's lifetime.

     Option:

     -f file	 Read from file rather than the default accounting file.

     -w 	 Use as many columns as needed to print the output instead of limiting it to 80.

     If called with arguments, only accounting entries with a matching command name, user name, or terminal name are printed.  So, for example:

	   lastcomm a.out root ttyd0

     would produce a listing of all the executions of commands named a.out by user root on the terminal ttyd0.

     For each process entry, the following are printed.

	   o   The name of the user who ran the process.
	   o   Flags, as accumulated by the accounting facilities in the system.
	   o   The command name under which the process was called.
	   o   The amount of cpu time used by the process (in seconds).
	   o   The time the process started.
	   o   The elapsed time of the process.

     The flags are encoded as follows: ``S'' indicates the command was executed by the super-user, ``F'' indicates the command ran after a fork,
     but without a following exec(3), ``C'' indicates the command was run in PDP-11 compatibility mode (VAX only), ``D'' indicates the command
     terminated with the generation of a core file, and ``X'' indicates the command was terminated with a signal.

     The ``S'' and ``C'' flags are no longer recorded by the system, but will be reported by lastcomm when reading from an accounting file gener-
     ated by an older version of the system.

FILES

     /var/account/acct	Default accounting file.
