The rsync command is used to synchronize and transfer the files in Linux. It synchronizes files between two local systems, directories, or a network. The basic rsync command contains the following:

rsync
For example, let’s synchronize between Documents and the Downloads directory. For this, you need to run the following command:

rsync -av ~/Documents ~/Downloads
If you want to go one step further, then you can use the below command:

rsync -avz –delete ~/Documents ~/Downloads
In the above command:

The -a option preserves all the permissions and other attributes
The -v option displays the detailed output of the synchronization
The -z allows compression that decreases the bandwidth use.
The –delete option removes the file in the Downloads that do not exist in the Documents directory.
