BABY(1) USER COMMANDS BABY(1)
NAME
BABY - create new process from two parent processes
SYNOPSIS
BABY [ -sex ] [ -name ]
DESCRIPTION
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 its final stages of execution.
Older implementations 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.
OPTIONS
-sex
option indicating type of process created.
-name
process identification to be attached to the new process.
RESULT
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.
BUGS
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.
