rsync is a powerful tool with many useful options. Here’s a quick list of examples:

1. -a: Archive mode, preserving symbolic links, devices, attributes, permissions, and ownership.

   Code Block
   rsync -a /path/to/source/ /path/to/destination/directory/

2. -v: Verbose mode, providing detailed information during the transfer.

   Code Block
   rsync -v /path/to/source/ /path/to/destination/directory/

3. -r: Recursively syncs folders.

   Code Block
   rsync -r /path/to/source/ /path/to/destination/directory/

4. -nv: Performs a verbose dry run, showing what the command would do without actually making any changes.

   Code Block
   rsync -nv /path/to/source/ /path/to/destination/directory/

5. -z: Compresses the data during transfer to save bandwidth.

   Code Block
   rsync -az /path/to/source/ /path/to/destination/directory/

6. -P: Combines --partial and --progress, keeping partially transferred files and showing progress during transfer.

   Code Block
   rsync -P /path/to/source/ /path/to/destination/directory/

7. --delete: Deletes files in the destination that are not present in the source, ensuring the destination is an exact mirror of the source.

   Code Block
   rsync -av --delete /path/to/source/ /path/to/destination/directory/

8. -t: Preserves modification times of files.

   Code Block
   rsync -t /path/to/source/ /path/to/destination/directory/

9. --exclude: Excludes files matching specified patterns from the transfer.

   Code Block
   rsync -av --exclude='*.tmp' /path/to/source/ /path/to/destination/directory/

10. --include: Overrides exclusions for specific patterns.
