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  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.

FILES

   acct
          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.
