Thank you but I think you misunderstood, without the domain extension, without .com, .net, .org or other domain extension. it must be something generic because I don't know the domain extension.
The examples above should be:
devmydomain (without com)
mydomain (without com)

Code:
> cat infile
dev.mydomain.com
mydomain.com
usca.berkeley.edu

Code:
perl -ne '@_ = split /\./;for ($i=0;$i<scalar(@_)-1;$i++) {print @_[$i]};print "\n"' infile

Code:
> perl -ne '@_ = split /\./;for ($i=0;$i<scalar(@_)-1;$i++) {print @_[$i]};print "\n"' infile
devmydomain
mydomain
uscaberkeley

Well,
Code:
j=${i%.*}
dom=${j//.}

or
Code:
dom=$(echo $i|sed -e's/\.[^.]*$//;s/\.//g')

or
Code:
dom=$(echo ${i%.*}|sed -e's/\.//g')

Would take care of that. But there are also various top level domains in two parts, e.g. .co.uk or .co.au. You would have to write exceptions for those cases if you want to cover everything.
