I’ve already written about a shell script to check / monitor domain renew / expiration date here. Now I’ve modified matt’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 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.
Sample usage
Display expiration date and registrar for theos.in domain:
domain-check-2 -d {domain-name}
$ domain-check-2 -d theos.in
Output:
Domain Registrar Status Expires Days Left
----------------------------------- ----------------- -------- ----------- ---------
theos.in et4India (R7-AFIN Valid 28-Oct-2009 799
You can also get an email if theos.in going to expire in 30 days
domain-check-2 -a -d theos.in -q -x 30 -e vivek@nixcraft.com
However most killer feature is you can read list of domain names from a file such as mydomains.txt (list each domain on a new line):
$ domain-check-2 -a -f mydomains.txt -q -x 30 -e vivek@nixcraft.com
$ domain-check-2 -f mydomains.txt
Output:
Domain Registrar Status Expires Days Left
