lastcomm(1)                      User Commands                     lastcomm(1)

       lastcomm - display the last commands executed, in reverse order

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

       The lastcomm command gives information on previously executed commands.
       lastcomm  with no arguments displays information 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 process account-
       ing  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  standard  process accounting is active, lastcomm
       takes data from the current standard accounting file (see acct(2)).

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

       For each process entry, lastcomm displays the following items of infor-

         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

         o  The amount of CPU time used by the process (in seconds).

         o  The date and time the process exited.

       The following options are supported:

       -f file         Uses file as the source of accounting data. file may be
                       either  an  extended process accounting file or a stan-
                       dard process accounting file.

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

       Example 1: Listing executions of named commands

       The command

       example% lastcomm a.out root term/01

       produces a listing of all the executions of  commands  named  a.out  by
       user root while using the terminal term/01.

       Example 2: Listing all user commands

       The command

       example% lastcomm root

       produces a listing of all the commands executed by user root.

       /var/adm/pacct                  standard accounting file

       /var/adm/exacct/proc            extended accounting file
