 `lastcomm'
 **********
 
    `lastcomm' prints out information about previously executed
 commands.  If no arguments are specified, `lastcomm' will print info
 about all of the commands in the `acct' file (the record file).  If
 called with a command name, user name, or tty name, only records
 containing those items will be displayed.  For example, to find out
 which users used command `a.out' and which users were logged into
 `tty0', type:
 
    `lastcomm a.out tty0'
 
    This will print any entry for which `a.out' or `tty0' matches in any
 of the record's fields (command, name, or tty).  If you want to find
 only items that match ALL of the arguments on the command line, you
 must use the '-strict-match' option.  For example, to list all of the
 executions of command `a.out' by user `root' on terminal `tty0', type:
 
    `lastcomm --strict-match a.out root tty0'
 
    The order of the arguments is not important.
 
    For each entry the following information is printed:
 
    * command name of the process
 
    * flags, as recorded by the system accounting routines:
         - *S* command executed by super-user
 
         - *F* command executed after a fork but without a following exec
 
         - *C* command run in PDP-11 compatibility mode (VAX only)
 
         - *D* command terminated with the generation of a core file
 
         - *X* command was terminated with the signal SIGTERM
 
    * the name of the user who ran the process
 
    * time the process exited
 
 Flags
 =====
 
    This program implements the features of regular u*x `lastcomm' with
 a few extra flags.  When `lastcomm' is invoked without arguments, the
 output looks like this:
      nslookup         jberman  ttypb      0.03 secs Tue Feb 16 19:23
      comsat           root     __         0.03 secs Tue Feb 16 19:19
      uptime           ctilburg __         0.11 secs Tue Feb 16 19:23
      sh          F    ctilburg __         0.02 secs Tue Feb 16 19:23
      sleep            ctilburg __         0.02 secs Tue Feb 16 19:22
      ls               noel     ttyp4      0.19 secs Tue Feb 16 19:23
 
 `--strict-match'
      Print only entries that match *all* of the arguments on the command
      line.
 
 `--user NAME'
      List records for user with NAME.  This is useful if you're trying
      to match a username that happens to be the same as a command (e.g.,
      `ed').
 
 `--command NAME'
      List records for command NAME.
 
 `--tty NAME'
      List records for tty NAME.
 
 `-f FILENAME'
 `--file FILENAME'
      Read from the file FILENAME instead of the system's `acct' file.
 
 `--debug'
      Print verbose internal information.
 
 `--version'
      Print `lastcomm''s version number.
 
 `--help'
      Print `lastcomm''s usage string and default locations of system
      files to standard output.
