  43 .Nm
  44 .Op Fl f Ar file
  45 .Op Ar command ...

  47 .Op Ar terminal ...
  48 .Sh DESCRIPTION
  49 .Nm
  50 gives information on previously executed commands.
  51 With no arguments,
  52 .Nm
  53 prints information about all the commands recorded
  54 during the current accounting file's lifetime.

  63 accounting file.
  64 .El
  65 .Pp
  66 If called with arguments, only accounting entries with a
  67 matching
  68 .Ar command
  69 name,
  70 .Ar user
  71 name,
  72 or
  73 .Ar terminal
  74 name
  75 are printed.
  76 So, for example:
  77 .Pp
  78 .Dl lastcomm a.out root ttyd0
  79 .Pp
  80 would produce a listing of all the
  81 executions of commands named
  82 .Pa a.out
  83 by user
  84 .Ar root
  85 on the terminal
  86 .Ar ttyd0  .

  99 .It
 100 The time the process started.
 101 .It
 102 The elapsed time of the process.
 103 .El
 104 .Pp
 105 The flags are encoded as follows: ``S'' indicates the command was
 106 executed by the super-user, ``F'' indicates the command ran after
 107 a fork, but without a following
 108 .Xr exec ,
 109 ``C'' indicates the command was run in PDP-11 compatibility mode
 110 (VAX only),
 111 ``D'' indicates the command terminated with the generation of a
 112 .Pa core
 113 file, and ``X'' indicates the command was terminated with a signal.
 114 .Sh FILES
