Write a single command including a regular expression to find all usernames and domains that eliminates duplicates, includes only the matching search hit text, excluding line numbers, and redirects the output to a text file.
Remember that a username can include letters, numbers and special characters. What I have written will run when [:punct:] is not present. Please let me know I need to fix. Thanks!
egrep -ro 'b[[:alnum:]][[:punct:]]+@[[:alnum:]][[:punct:]]+.[[:alpha:]]+b'
grep

What usernames and domains? You need to give an input sample with your desired output from it for text processing
