BABY(1) USER COMMANDS BABY(1)
BABY - create new process from two parent processes
BABY sex [ name ]
SYSTEM V SYNOPSIS
/usr/5bin/BABY [ -sex ] [ -name ]
The System V version of this command is available with the Sys-
tem 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 monitoring 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.

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 requiring /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.
