Grep by email with an exception from the result, a specific domain (for example mail.ru)?

Question

SSH

Good day to all!
The essence of the problem is to select all lines with email addresses from the maillog, but excluding mailboxes from the *@mail.ru domain from the result

grep  '[[:alnum:]+\.\_\-]*@[[:alnum:]+\.\_\-]*' ./maillog | grep -v '*@mail\.ru'

Doesn't work, please tell me where is the error?

Answer 1

Actually, you should use grep -E.
I also recommend adding an argument -o.
