What do -v and -z options do?

In the context of the rsync command, the -v and -z options have the following functions:

1. -v (Verbose):

   • This option enables verbose output. It provides detailed information about the files being transferred, including their names and the progress of the transfer. This is useful for monitoring what rsync is doing during the operation.

2. -z (Compress):

   • This option enables compression during the transfer. It reduces the amount of data sent over the network by compressing files before they are transmitted. This can speed up the transfer process, especially for large files or when transferring over slow connections.

Here’s an example of how you might use these options together:

rsync -avz source/ destination/

In this command, -a is also included for archive mode, which preserves permissions and timestamps, while -v provides verbose output and -z compresses the data during transfer.
