  1. Good job, script works on MAC OSX/LION:

  2. I tried using above script on CentOS 6 but the same is not working and giving error as

    ./searchdomain.sh google.co.in yahoo.co.in
    ./searchdomain.sh: line 22: host: command not found
    Error: google.co.in is not valid domain or dns error.
    ./searchdomain.sh: line 22: host: command not found
    Error: yahoo.co.in is not valid domain or dns error.
    Please advise

  3. Hi I am using CentOS 5.6 (64 bit)
    I am getting nothing while running this script
    My output is —

    [root@svn ~]# ./521.sh cyberciti.biz http://www.google.com
    Getting information for domain: cyberciti.biz [ 75.126.153.206 ]…

    Getting information for domain: http://www.google.com [ 74.125.236.52 ]…

    [root@svn ~]

    Can you please help me on that

    1. Hi , i get the same as DeepakSharma , i was wondering does anyone know what this is about ? Im using Fedora 15 , 64bit .
      /e I tryed “whois” command but i dont have so i replaced it with “who” , maybe thats the reason? Any ideas in general ? :)

      1. The issue is because of the egrep command – currently its filtering the lines starting with OrgName:|City:|Country:|OriginAS:|NetRange:

        but .org .biz and some other TLDs use a bit different wording – try to change line:
        whois “$_ip” | egrep -w ‘OrgName:|City:|Country:|OriginAS:|NetRange:’

        with

        whois “$_ip” | egrep -w ‘OrgName:|City:|Country:|OriginAS:|NetRange:|inetnum|address|descr’

        at least that works good enough for me.

        Cheers,
        Stanimir

        1. How about this one? This fixed it on my centos 5.8 box:

  4. There is no need to use three programs if you can do it with one.

    should read

  5. – You should not use [ but [[
    – You should not use this as a valid test [ “$_ip” == “” ]
    but test the return value [[ $? -eq 0 ]]
