Parse string

Hi, I need to parse a string, check if there are periods and strip the string.
For example i have the following domains and subdomains: mydomain.com, dev.mydomain.com

I need to strip all periods so i have a string without periods or domain extensions: mydomain, devmydomain.

I use this for domains but i don't know how to do it for subdomains also
Code:
dom=(`echo $i | tr '.' ' '`)

Thank you

With awk:

Code:
echo "dev.mydomain.com" | awk -F"." '{print $(NF-1)}'

Code:
dom=${i//.}

Unfortunately it doesn't work because I don't know if will be a domain or a subdomain. If the output is:
mydomain.com
dev.mydomain.com

I need to parse each string and strip the domain and periods.It works with tr but the problem is how do i check if it's a subdomain.For the two strings above it should result:

mydomain
devmydomain

Yes it does work. Did you try?

Code:
$ echo "dev.mydomain.com" | awk -F"." '{print $(NF-1)}'
mydomain
$ echo "mydomain.com" | awk -F"." '{print $(NF-1)}'
mydomain

Oops misread you requirements...
I guess you would need two statements
Code:
j=${i/.com}
dom=${j//.}

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

Thank you, it works but for different domain extensions like .net, .org ..ow do I do it ? I don't know what domain extension would be, it could be .net or aomething else
