NAME
       lastcomm -  print out information about previously executed commands.

SYNOPSIS
       lastcomm
              [ command-name ...  ]
              [ user-name ...  ]
              [ 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 ter-
       minal-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 ei-
              ther 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.
