How to grep against a list of domains without using a bash script
I have been given a list of disposable emails and other emails that my company does not want in our mailing list and asked to remove them. I know grep -v or awk !/xxx/' but this is against a list of 1000 email domains they do not want. I could use a bash script but they are only being sorted one at a time which still leave manual sorting. Any ideas are welcone please
awk sed grep email domain

So, you have a mailing list file "A". You also have a thousand-plus lines list of domains and email addresses "B" to remove from the mailing list file. You want a fairly rapid automated method to remove B from A. Is that correct? Please click edit and clarify your question.

If I understand you correctly you have a file that is a mailing list.
$ cat mail_list
email1@domain1.com
email2@domain2.com
email3@domain3.com
email4@domain4.com
email5@domain5.com
You have a file that is a black list.
$ cat blacklist
email2@domain2.com
email4@domain4.com
You want to make a new mailing list file with the email addresses in the black list removed?
Using the blacklist file with grep:
-f file, --file=file
Read one or more newline separated patterns from file. Empty pattern lines match every input line. Newlines are not considered part of a pattern. If
file is empty, nothing is matched.
$ grep -vxFf blacklist mail_list
email1@domain1.com
email3@domain3.com
email5@domain5.com
To make a new mailing list you would redirect this into the file like:
$ grep -vxFf blacklist mail_list > new_mail_list
Which you could then use to overwrite the old mail list
$ mv new_mail_list mail_list
