How To Use wget With Username and Password for FTP / HTTP File Retrieval

The wget command is a command-line utility for downloading files from the web. It can be used to download files from FTP and HTTP servers, as well as HTTPS servers with SSL/TLS support.

To use wget to download a file from an FTP or HTTP server that requires a username and password, you can use the --user and --password options, like this:

wget --user=username --password=password ftp://ftp.example.com/path/to/file

This will download the file file from the FTP server ftp.example.com using the specified username and password.

Alternatively, you can also specify the username and password in the URL itself, like this:

wget ftp://username:password@ftp.example.com/path/to/file

This will have the same effect as the previous command, but the username and password will be encoded in the URL.

Keep in mind that using the --user and --password options or encoding the username and password in the URL can be considered a security risk, as it exposes the credentials in plain text.

If you need to download a file from an HTTPS server with SSL/TLS support, you can use the --no-check-certificate option to disable certificate validation. This can be useful when connecting to an HTTPS server with a self-signed certificate.
