Extract parent domain name from a list of url through Bash ShellScripting

I have a list of urls like this:

http://noto.zrobimystrone.pl/pucenter/images/NGdocs/

I wanna extract only the parents domain names, for example:

http://noto.zrobimystrone.pl/pucenter/images/NGdocs/
http://visionwebmkt.com/unsubscribe.php?M=879552&C=b744d324e38f5f3b0bcf549f1d57a3ab&L=20&N=497
http://www.meguiatramandai.com.br/unsubscribe.php?M=722&C=8410431be55bf12faac13d18

Into

zrobimystrone.pl
visionwebmkt.com
meguiatramandai.com.br

I have tried

awk '{gsub("http://|/.*","")}1' list.txt

and got the following results:

noto.zrobimystrone.pl
visionwebmkt.com
www.meguiatramandai.com.br
www.contatoruy.in
www.maxxivrimoveis.com.br
www.meguiatramandai.com.br
arm.smilecire.com
hurl.zonalrems.com
harp.doomyjupe.com
beefy.toneyvaws.com

but dont know how to get only the parent name from noto.zrobimystrone.pl for instance.

You can use this awk:

awk -F'.' '{gsub("http://|/.*","")} NF>2{$1="";$0=substr($0, 2)}1' OFS='.' list.txt
zrobimystrone.pl
visionwebmkt.com
meguiatramandai.com.br

A "simple" bash solution. Tested in bash shell on Solaris 11.2 x86.

#!/bin/bash
while IFS=/ read HTTP NULL FQDN PAGE
do
    PARENT=${FQDN#*.}
    if [[ $PARENT != *"."* ]]
        then echo $FQDN
        else echo $PARENT
    fi
done < fileOfURLs.txt

Without the string contains pattern test, too much of the domain could be stripped away. The if paragraph can be reduced,so the whole script now looks like this:

#!/bin/bash
while IFS=/ read HTTP NULL FQDN PAGE
do
    PARENT=${FQDN#*.}
    [[ $PARENT != *"."* ]] && echo $FQDN || echo $PARENT
done < fileOfURLs.txt

The bash variable substitution is taking the contents of the variable FQDN and stripping from the left any character up to and including the first dot.

The test condition is asking if the contents of the PARENT variable does not contain a dot. If it does not hold a dot somewhere in the value, the test evaluates to true and will display the original FQDN contents. If the test evaluates to false, (there is still a dot in the value) the contents of PARENT are displayed.
