              [ terminal-name ...  ]
              [ --strict-match ]
              [ --forwards ]
              [ -f filename | --file filename ] [ --ahz hz ]
              [ --user name ] [ --command name ] [ --tty name ]

              | --show_paging ] [ --debug ] [ -V | --version ] [ -h | --help ]

DESCRIPTION

       lastcomm prints out information about previously executed commands.  If no  arguments  are
       specified,  lastcomm  will print info about all of the commands in acct (the record file).
       If called with one or more of command-name,  user-name,  or  terminal-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 terminal).  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 --command a.out --user root --tty 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 started

OPTIONS

       --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.
       --forwards
              Read file forwards instead of backwards. This avoids trying to seek on the file and
              can be used to read from a pipe. This must be specified prior to any -f arguments.
       -f filename, --file filename
              Read  from  the  file  filename  instead of acct.  A filename of "-" will result in
              reading from stdin. This must either be the first -f  option,  or  --forwards  must
              precede all -f options.
       --ahz hz
              Use  this  flag  to tell the program what AHZ should be (in hertz).  This option is
              useful if you are trying to view an acct file created on another machine which  has
              the  same  byte  order and file format as your current machine, but has a different
              value for AHZ.
       -p, --show-paging
              Print paging statistics
       --debug
              Print verbose internal information.
       -V, --version
              Print the version number of lastcomm.
       -h, --help
              Prints the usage string and default locations of system files  to  standard  output
              and exits.
