+# to alarm if a domain is about to expire.
+#
+# License:
+# This program is distributed in the hope that it will be useful,
+# but WITHOUT ANY WARRANTY; without even the implied warranty of
+# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
+#
+# Notes:
+# Since each registrar provides expiration data in a unique format (if
+# they provide it at all), domain-check is currently only able to
+# processess expiration information for a subset of the available
+# registrars.
+#
+# Requirements:
+# Requires whois
+#
+# Installation:
+# Copy the shell script to a suitable location
+#
+# Tested platforms:
+# -- Solaris 9 using /bin/bash
+# -- Solaris 10 using /bin/bash
+# -- OS X 10.4.2 using /bin/sh
+# -- OpenBSD using /bin/sh
+# -- FreeBSD using /bin/sh
+# -- Redhat advanced server 3.0MU3 using /bin/sh
+#
+# Usage:
+# Refer to the usage() sub-routine, or invoke domain-check
+# with the "-h" option.
+#
+# Example:
+#
+# The first example will print the expiration date and registrar for prefetch.net:
+#
+# $ domain-check.sh -d prefetch.net
+#
+# Domain Registrar Status Expires Days Left
+# ----------------------------------- ----------------- -------- ----------- ---------
+# prefetch.net INTERCOSMOS MEDIA Valid 13-feb-2006 64
+#
+# The second example prints the expiration date and registrar for the domains
+# listed in the file "domains":
+#
+# $ domain-check.sh -f domains
+#
+# Domain Registrar Status Expires Days Left
+# ----------------------------------- ----------------- -------- ----------- ---------
+# sun.com NETWORK SOLUTIONS Valid 20-mar-2010 1560
+# google.com EMARKMONITOR INC. Valid 14-sep-2011 2103
+# ack.com NETWORK SOLUTIONS Valid 09-may-2008 880
+# prefetch.net INTERCOSMOS MEDIA Valid 13-feb-2006 64
+# spotch.com GANDI Valid 03-dec-2006 357
+#
+# The third example will e-mail the address admin@prefetch.net with the domains that
+# will expire in 60-days or less:
+#
+# $ domain-check -a -f domains -q -x 60 -e admin@prefetch.net
+#
+
+PATH=/bin:/usr/bin:/usr/local/bin:/usr/local/ssl/bin:/usr/sfw/bin ; export PATH
+
+# Who to page when an expired domain is detected (cmdline: -e)
+ADMIN="sysadmin@mydomain.com"
+
+# Number of days in the warning threshhold (cmdline: -x)
+WARNDAYS=30
+
+# If QUIET is set to TRUE, don't print anything on the console (cmdline: -q)
+QUIET="FALSE"
+
+# Don't send emails by default (cmdline: -a)
+ALARM="FALSE"
+
+# Whois server to use (cmdline: -s)
+WHOIS_SERVER="whois.internic.org"
+
+# Location of system binaries
+AWK="/usr/bin/awk"
+WHOIS="/usr/bin/whois"
