According to the ISO standard:

Quote:

All ASCII ccTLD identifiers are two letters long, and all two-letter top-level domains are ccTLDs.

Thus, you could assume that any domain ending in a two character code should print the last two subdomain names in addition to the top level domain:

Code:

# assume url is first field; change if needed
awk '
        {
                gsub( "^.*://", "", $1 );      # ditch the http://  ftp:// etc
                n = split( $1, a, "." );
                if( length( a[n] ) == 2 )       # assuming all two character top level domains are country codes
                        printf( "%s.%s.%s\n", a[n-2], a[n-1], a[n] );
                else
                        printf( "%s.%s\n",  a[n-1], a[n] );
        }
' list-file-name

This also takes into account that

Code:

http://foo.com

should not print anything before the double slants. Caution may need to be exercised as some countries have licensed the use of their top level domain name (e.g. .tv and .fm).
