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

     lastcomm -- show last commands executed in	reverse	order

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

     Lastcomm gives information	on previously executed commands.  With no ar-
     guments, lastcomm prints information about	all the	commands recorded dur-
     ing 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, ``D'' indicates the command terminated with
     the generation of a core file, and	``X'' indicates	the command was	termi-
     nated with	a signal.

     /var/account/acct	Default	accounting file.

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

     The lastcomm command appeared in 3.0BSD.
