Here’s a script to track Twitter unfollowers. It it based on @sferik‘s excellent command-line Ruby Twitter client ‘t’. Visit its GitHub page for installation instructions; they’re pretty straightforward.
The script is quick and dirty but easy to follow: it compares a new followers list to the previous list followers list and e-mails you the difference.
While it is technically very easy to automatically unfollow back I highly recommend against it, following my recent screw-up when I accidentally unfollowed over two thousand followers. E-mail notifications are the way to go.
Make sure you’re server is set up to send out mail and change that part accordingly. If it isn’t I recommend a Google search for “ssmtp gmail”. That’s an easy way to have your server send out mail using your Gmail account.
Note that Twitter queries use api calls. I recommend agains running the script too often. Once an our or once a day.
The script was written for Bash on Debian 8. Should work on any major Linux distro.
