What's Wrong?

Base64 or any inline Stays infinitely reading the one line, need to use grep or detect line length before reading it. Or just detect base64 and DONT read it, just use it with a script as you do.

What Should Happen?

It should not read it, just know its a base64... decode it if needed, but usually no need.

Steps to Reproduce

Have a file converted to base64, maybe save it as a txt for convenience. then tell it to use that base64 to send it somewhere, and it stays reading 1 infinite line...
