Bash script to remove email addresses from a csv file of users exported from website or database
This is a rather odd and specific script for quickly eliminating certain emails from a set of emails contained in a csv file.
Due to some rather odd operating requirements, we found ourselves with a csv export of users from a database. We needed to send emails to these users, but not all of them (a.k.a a list of do not contacts or bad emails). Since, for whatever reason, we couldn't actually do this in the database, I threw together this script that does it.
The main csv file containing the emails in the 13th column
The text file containing the emails you want removed from the list. Each email should be on its own line in quotes.
By defualt the script prints to the screen. However, by using the redirection operator >> you can point the output into
any file you want.
