Diff without details – show only file names

If you’re interested only in finding out the files that may have changed and not necessarily the content, you could use diff with -q to return only filenames

diff -qr dirStage dirProd

It gets even better. If you’re comparing stage and prod environments, you’re likely to have log, pyc, db backups and other files that you don’t care about. Here’s how you can ignore unwanted file types using the -x argument:

diff -qr -x '*.pyc' -x '*.log' -x '*.sql' -x '*.txt' dirStage dirProd
