echo doesn't read from stdin, are you sure you should be piping to it?

Problematic code:

find . | echo

Correct code:

find .

Rationale:

You are piping command output to echo, but echo ignores all piped input.

In particular, echo is not responsible for putting output on screen. Commands already output data, and with no further actions that will end up on screen.

Exceptions:

None.
