User Commands                                         lastcomm(1)



NAME
     lastcomm - display the last commands  executed,  in  reverse
     order

SYNOPSIS
     lastcomm [-f file] [-x] [command-name] ... [user-name] ...
          [terminal-name] ...


DESCRIPTION
     The lastcomm command gives information  on  previously  exe-
     cuted commands. lastcomm with no arguments displays informa-
     tion about all the  commands  recorded  during  the  current
     accounting   file's  lifetime.  If  called  with  arguments,
     lastcomm only displays accounting entries  with  a  matching
     command-name,  user-name, or terminal-name. If extended pro-
     cess accounting is active (see acctadm(1M)) and is recording
     the  appropriate  data items, lastcomm attempts to take data
     from the current extended process accounting file. If  stan-
     dard  process accounting is active, lastcomm takes data from
     the current standard accounting file (see acct(2)).


     If terminal-name is `- -', there was no controlling TY  for
     the  process.  The process was probably executed during boot
     time. If  terminal-name is `??', the controlling  TY  could
     not be decoded into a printable name.


     For each process  entry,  lastcomm  displays  the  following
     items of information:

         o    The  command  name  under  which  the  process  was
              called.

         o    One or more flags  indicating  special  information
              about  the  process.  The  flags have the following
              meanings:


              F    The process performed a fork but not an exec.


              S    The process ran as a set-user-id program.



         o    The name of the user who ran the process.

         o    The terminal which the user was logged in on at the
              time (if applicable).

                may be either an extended process accounting file
                or a standard process accounting file.


     -x         Uses  the  currently  active   extended   process
                accounting  file. If extended processing account-
                ing is inactive, no output will be produced.
