Need to find occurrences of email domains in all files in a directory
Hello Everyone!

I trust you are off to a great week! Trying to output the name and count of each uniquely occurring domain in the current directory for a portion of a script I'm building.

Here's what I'm stuck on:

- Need to find UNIQUE occurences of domains (*@domain.com) in ALL files in a directory.
- Need to output:
uniquedomain1.com = 1234 occurrences
uniquedomain2.com = 12345 occurrences
... etc

- Every file includes ONE domain per line, with the format of the surrounding text being inconsistent and random. What WILL remain consistent is that each line will have an email address with the following syntax somewhere in each: emailaddress@domain.com


Would someone be able to help me figure out how do this?

Thanks so much

I can call the below to output a list of UNIQUELY occuring domains:
perl -wne'while(/@[\w\.]+/g){print "$&\n"}' filename | sort -u

Now, how do I, for all files in a directory, display the count of each unique domain per file and then a final TOTAL count, per domain, for all files.

Thanks!
