The word daemon is derived from the Greek word daimon, meaning a
"supernatural being" or "spirit", rather than demon, referring to the
fallen angels or followers of Satan. Some would insist that Unix is
infested with both daemons and demons. In Unix, daemons are typically
started by the root process when the operating system is initialized,
and run in the background indefinitely. Daemons typically spend most
of their time waiting for an event or period when they will perform
some task. Examples of common Internet daemons include WU-Ftpd,
Apache, BIND, and Sendmail. These particular daemon programs are
responsible in part for making the Internet useful, but daemons also
serve other purposes that are not as visible to users. In this
tutorial, we'll learn how easy it is to turn a Perl script into a
daemon process.
