OSX SSH rsync - Keep remote directory up to date

alias run_rsync='rsync -azP --exclude ".*/" --exclude ".*" --exclude "tmp/" /source_folder username@host:/destination_folder'
run_rsync; fswatch -o . | while read f; do run_rsync; done

Second line runs run_rsync once unconditionally and then - on each change in current directory (or specify exact path instead of .)

You will need fswatch - here is how to install via brew:

brew install fswatch

Rsync options:

• -a - stands for "archive" and syncs recursively and preserves symbolic links, special and device files, modification times, group, owner, and permissions.
• -z - compression
• -P - combines the flags --progress and --partial. The first of these gives you a progress bar for the transfers and the second allows you to resume interrupted transfers
• --exclude - excludes files by pattern
