For reading, it expects the data to be all on one line (with or without a trailing newline). Base64 Encoding Base64 Decoding Base64 encode the string "Hello World\n" and write the result to standard output: Read Base64 encoded data from standard input and write the decoded data to standard output: The ambiguity of EOF in base64 encoded data can cause additional data following the base64 encoded block to be misinterpreted. Because xxd ignores any trailing newline in the input, echo or echo -n will behave precisely the same here; whether there's a newline by echo makes no difference, because that newline (if it exists) will be consumed by xxd when reading its input.
