LASTCOMM(1)		FreeBSD	General	Commands Manual		   LASTCOMM(1)

NAME
     lastcomm -- show last commands executed in	reverse	order

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

DESCRIPTION
     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 options are as	follows:

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

     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   Name of the user	who ran	the process.
	   +o   Flags, as accumulated by	the system's accounting	facilities.
	   +o   Command name under which	the process was	called.
	   +o   Amount of CPU time used by the process (in seconds).
	   +o   Time the	process	started.
	   +o   Elapsed time of the process.

     The flags are encoded as follows:

	   D	   The command terminated with the generation of a core	file.
	   F	   The command ran after a fork, but without a following
		   execve(2).
	   M	   The command did a system call from writable memory or the
		   stack pointer was not in stack memory.
	   P	   The command was terminated due to a pledge(2) violation.
	   T	   The command did a memory access violation detected by a
		   processor trap.
	   U	   The command tried a file access that	was prevented by
		   unveil(2).
	   X	   The command was terminated with a signal.
