       lastcomm -  print out information about previously executed commands.


              [ 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 ]


       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


              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.
              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
              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.


              The  system  wide  process  accounting  file.  See  acct(5)  (or
              pacct(5)) for further details.  /var/log/account
                     This directory contains pacct  files  which  contain  the
                     binary  process accounting data as written by the kernel.
