I'm a total novice trying to get a Bash script to work for pulling files from a remote server via SFTP. The script I wrote connects fine and transfers files, but I'm having trouble with the notification logic. It seems to always report changes even when there are none. If anyone could offer some insights into potential limitations or issues with my approach—or better yet, any advice on improving the script—I'd appreciate it! Oh, and if you could help me format the code properly for posting, that would also be great!

If your source and destination support rsync, try using it with the `--itemize-changes` flag. This way, you'll get detailed output about what changed and can use that for your notifications. Just make sure to set up your notifications based on that output—it's more reliable! And for larger scripts, it might help to share it on a site like gist.github.com for clearer visibility.
Your script looks solid, but I think the issue may be in how you're checking for changes. Make sure you’re capturing the output of the SFTP correctly and that your logic accurately reflects the state of file changes. Adding some debugging messages can help you track what’s happening when you run the script. Good luck!
To format your script correctly when posting, remember to indent it with four spaces for each line, and add a blank line above and below your code block. This helps others read your code more easily! Also, consider using a tool like shellcheck to improve your code and catch any errors—it's super helpful for beginners. Good luck!
Thanks for the tip! Is there a quicker way to indent the code all at once?
