baby – create new process from two parent processes


baby sex [ name ]


/usr/5bin/baby [ -sex ] [ -name ]


The System V version of this command is available with the System V software installation option. Refer to Installing SunOS 4.1 for information on how to install and invoke baby.


baby is initiated when one parent process polls another server process through a socket connection (BSD) or through pipes in the system V implementation. baby runs at a low priority for approximately 40 weeks then terminates with heavy system load. Most systems require constant monitering when baby reaches it’s final stages of execution.

Older implentations of baby required that the initiating process not be present at the time of completion, In these versions the initiating process is awakened and notified of the results upon completion. Modern versions allow both parent processes to be active during the final stages of baby.

-sex option indicating type of process created.

-name process identification to be attaced to the new process.


Successful execution of the baby(1) results in new process being created and named. Parent processes then typically broadcast messages to all other processes informing them of their new status in the system.


The SLEEP command may not work on either parent processes for some time afterward, as new baby processes constantly send interrupts which must be handled by one or more parent.

baby processes upon being created may frequently dump in /tmp requireing /tmp to be cleaned out frequently by one of the parent processes.

The original AT&T version was provided without instuctions regarding the created process, this remains in current implementations.

FSF version of baby where none of the authors will accept responsibility for anything.


baby -sex f -name Cathryn Leigh Beck completed sucessfully at the Grey Nuns Hospital on March 30 at 9:59 P.M. after 5 hours of labour. New Mom Chenelle is doing fine, as is the baby, Dad is tickled pink. Both will probably come home sometime on Teusday. More information can be gotten from Dad by e-mail or when he brings his new little girl by to show her off (should be soon) Celebrations can probably begin in earnest after Dad catches up on all the work he couldn’t do this weekend.

Sun Release 4.1 Last change: Just before I left the hospital last.
