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

     lastcomm -- show last commands executed in	reverse	order

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

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

     The following options are available:

     -E		Print the time the process exited.
     -S		Print the time the process started.
     -c		Print the amount of cpu	time used by the process.
     -e		Print the amount of elapsed time used by the process.
     -s		Print the amount of system time	used by	the process.
     -u		Print the amount of user time used by the process.
     -f	file	Read from file rather than the default /var/account/acct.

     If	no options are specified, -cS is assumed.  If lastcomm is invoked with
     arguments,	only accounting	entries	with a matching	command	name, user
     name, or terminal name are	printed.  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 sys-
	   +o   The command name	under which the	process	was called.
	   +o   The amount of CPU (-c), wall (-e), system (-s), or user (-u)
	       time used by the	process	(in seconds).
	   +o   The time	the process started (-S) or exited (-E).

     The flags are encoded as follows: ``S'' indicates the command was exe-
     cuted by the super-user, ``F'' indicates the command ran after a fork,
     but without a following exec(3), ``D'' indicates the command terminated
     with the generation of a core file, and ``X'' indicates the command was
     terminated	with a signal.

     /var/account/acct	Default	accounting file.

     last(1), sigvec(2), acct(5), core(5)

     The lastcomm command appeared in 3.0BSD.
