I have a bunch of email addresses

abc@yahoo.com
defgh@google.com

I just want to keep the domains and strip of the name:
like: yahoo.com
google.com

How do you "have" them?

If they are in variables, use parameter expansion:

email=abc@yahoo.com
domain=${email#*@}


If they are in a file, use cut:

cut -d@ -f2 FILE

Or, if you need to manipulate the domains after extracting them:

while IFS=@ read a domain
do
## DO something with $domain here
done < FILE

Or:

awk -F@ '{ domain=$2
# do something with domain here
}' FILE
