baby -- create new process from two parents
baby -sex [m|f] [-name name]
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 sys-
tems require constant monitoring when baby reaches its
final stages of execution.
Older implementations of baby did not require both initi-
ating 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 com-
pletion. It has since been determined that the presence
of both parent processes result in a generally lower sys-
tem load at completion, and thus current versions of baby
expect both parent processes to be active during the final
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, inform-
ing them of their new status.

-name assign the name name to the new process

line's vital statistics: 8 pounds 3 oz, 20 inches, long
dark hair. The parent process, Kim Dunbar, is reportedly
cigar(6), dump(5), cry(3).
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 par-
ent processes must then inspect the baby process to deter-
mine the cause of the signal.
The sleep(1) 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 immedi-
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 over-
