Which command allows for a recursive download of the src share from a Samba server named SOURCES for anonymous users?

The command smbget is specifically designed for downloading files over the Samba (SMB/CIFS) protocol, making it the most suitable choice for this scenario involving an anonymous download from a Samba server. The recursive option, indicated by -R, enables users to download entire directories and their contents, which aligns perfectly with the requirement to retrieve the 'src' share in a recursive manner.

Using smbget is particularly advantageous in this context, as it supports various options that allow seamless interaction with Samba shares, including the handling of authentication for anonymous users. Therefore, it simplifies the process of downloading shared content from a Samba server.

Other choices, while they may appear viable, are not as appropriate for this specific task. Wget is primarily used for HTTP/HTTPS downloads and does not natively support the SMB protocol. Curl, while versatile for various protocols, does not inherently support Samba without significant additional configuration. Smbmirror, although capable of mirroring Samba shares, is not the best choice here since smbget is more straightforward for simply downloading files or directories recursively.

Overall, smbget not only fulfills the requirement of recursive downloading but also does so with the protocol explicitly used by Samba servers, making it the most effective and appropriate command in this case.
