Which command is specifically geared for quickly transferring files in a noninteractive manner between two systems on a network?

The command that is specifically geared for quickly transferring files in a noninteractive manner between two systems on a network is rsync. This tool is particularly effective for synchronizing files and directories, making it ideal for transferring only the differences between source and destination, which enhances speed and efficiency.

Rsync operates over SSH or can use other transfer methods, allowing users to see which files have changed since the last sync and only transferring those files, rather than the entire dataset. This capability is crucial in minimizing bandwidth usage and maximizing performance, particularly when dealing with large files or directories.

In contrast, while scp is also used for transferring files securely over a network, it does not have the same level of efficiency as rsync because it transfers the whole files without checking for updates or differences. SFTP and FTP are traditionally used for file transfers but are generally not as efficient in terms of synchronizing data or transferring only incremental changes, which is a significant advantage in environments where data can differ greatly between systems.
