Subject: Re: ot- my new baby!
Good for you. The facebook page isn't available right now so I guess
we'll have to wait to see the pictures. Here's a little something I
found at
http://www.linuxhowtos.org/System/man_baby.htm

% man baby


baby(1)                  USER COMMANDS                    baby(1)




NAME
      baby - create new process from two parents


SYNOPSIS
      baby -sex m | f [ -name name ]


DESCRIPTION
      Baby is initiated when  one  parent  process  polls  another
      server  process  through a socket connection in the BSD ver-
      sion or through pipes in the System V implementation.   Baby
      runs  at low priority for approximately forty weeks and then
      terminates with a heavy system load.  Most  systems  require
      constant  monitoring  when  baby reaches its final stages of
      execution.


      Older implentations of baby did not require both  initiating
      processes to be present at the time of completion.  In those
      versions the initiating process which was  not  present  was
      awakened  and  notified  of the results upon completion.  It
      has since been determined that the presence of  both  parent
      processes result in a generally lower system load at comple-
      tion, and thus current versions of baby expect  both  parent
      processes to be active during the final stages.


      Successful completion of baby results in  the  creation  and
      naming  of  a  new process.  Parent processes then broadcast
      messages to all other processes, local and remote, informing
      them of their new status.


OPTIONS
      -sex define the gender of the created process


      -name
           assign the name name to the new process


EXAMPLES
      baby -sex f -name Jacqueline


           Completed successfully on July  9,  1992 at 9:11pm.
           Jacqueline's vital  statistics:  8  pounds 3 oz, 20
           inches, long dark hair.  The parent process, Kim
           Dunbar, is  reportedly doing fine.


SEE ALSO
      cigar(6), dump(5), cry(3).


BUGS
      Despite its complexity, baby only knows one signal, SIGCHLD,
      (or SIGCLD in the System V implementation), which it uses to
      contact the parent processes.  One or both parent  processes
      must then inspect the baby process to determine the cause of
      the signal.




Sun Release 4.1     Last change: July 6, 1991                   1





baby(1)                  USER COMMANDS                    baby(1)




      The sleep command may not work as expected on either  parent
      process  for  some  time  afterward, as each new instance of
      baby sends intermittent  signals  to  the  parent  processes
      which must be handled by the parents immediately.


      A baby process will frequently dump core,  requiring  either
      or both parent processes to clean up after it.


      Despite the reams of available documentation on invoking and
      maintaining baby, most parent processes are overwhelmed.
