       lastcomm -  print out information about previously executed commands.


              [ command-name ...  ]
              [ user-name ...  ]
              [ terminal-name ...  ]
              [ OPTION ... ]


       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.
              Print control characters.
       --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.
       --pid  Show PID and PPID of the process if acct version 3 format is supported by kernel.
       --pid  Add pid of the process and pid of the process parent to the output (pid is the last
              but one and parent pid the last column).  These values are shown only when they are
              generated by acct function (depends on the version of kernel)
              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.
