## 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.
