I have already written a shell script to check/monitor domain renew / expiration date here. Now I have modified matty’s domain-check script to support additional C/TLDs .in, .biz, .org and .info domains. I’ve also added 5 seconds delay to avoid whois server rejecting the query. This script checks to see if a domain has expired. It can be run in interactive and batch mode and provides facilities to alarm if a domain is about to expire in advance.
This article explains – controlling the duration of scheduled jobs (at and cron jobs) under Linux using nice shell script tricks:
Say you need to debug a pesky problem by running some traces for 30 minutes at midnight, or you would just like to use your Linux system as an alarm clock. This tip helps you stop jobs, such as those started with the cron and at capabilities, after the jobs have run for a certain time, or when some other criteria are met.

Update: Check out new improved domain-check script.
Forgetting to renew your domain name can happen to all of us. According to this post:
Reports are coming in from Germany that Google.de was down for many hours yesterday, and has now gone live again. We’re trying to confirm the reason, but it appears to be because Google forgot to renew the Google.de domain name..
I am going to share my little (read as dirty) shell script. It monitors and lists domain expiration date.
whois command line client for the whois directory service. It provides domain whois information. To find out nixcraft.com domain information you need to type:
$ whois nixcraft.com
Find domain expiration date
To get expiration date use grep command:
$ whois nixcraft.com | egrep -i 'Expiration|Expires on'
Expiration Date: 10-may-2009
NOTICE: The expiration date displayed in this record is the date the
currently set to expire. This date does not necessarily reflect the expiration
view the registrar's reported date of expiration for this registration.
Expires on: 10-May-09
Here is my script:
# Domain name list - add your domainname here
DOM="theos.in cricketnow.in nixcraft.com nixcraft.org nixcraft.biz nixcraft.net nixcraft.info cyberciti.biz cyberciti.org gite.in nixcraft.in"
for d in $DOM
echo -n "$d - "
whois $d | egrep -i 'Expiration|Expires on' | head -1
# If you need list..
# whois $d | egrep -i 'Expiration|Expires on' | head -1 >> /tmp/domain.date
# [ -f /tmp/domain.date ] && mail -s 'Domain renew / expiration date' email@example.com < /tmp/domain.date || :
