Missing a new line and decode error about data-encoding HOT 2 CLOSED

Hi @QMHTMY ,

Thanks for your question!

I see the concern is only about newline regarding command line tools. So I'll first describe how they work:

• echo is a tool that prints its arguments, separated by spaces and followed by a newline. If you don't want the newline, you can use echo -n. For example echo abc outputs abc\n (i.e. 6162630a in hexa).
• data-encoding is a tool that converts strings without extra pretty-printing information, such that it can be used in more complex tools. For example echo -n abc | data-encoding -me -b64 outputs YWJj and not YWJj\n.
• Shells (like bash) have different ways to show whether a command output contains a newline or not. For example in bash, the prompt is on the same line.

To solve your problems:

1. If you want a newline after data-encoding output, you can use echo "$(echo -n abc | data-encoding -me -b64)".
2. To avoid the decoding error, you can remove the invalid newline in the input by using echo -n YWJj | data-encoding -md -b64 (or echo "$(echo -n YWJj | data-encoding -md -b64)" if you want a newline in the output)

Note that you can also ignore newlines when decoding. For example echo YWJj | data-encoding -md -b64 -g$'\n' (the actual syntax to pass a newline to -g depends on your shell).

Hope this helps
