If you need to print anything involving a backspace you should
use printf and not echo.

It's true that backslashes should not be passed to echo, but assuming unset or empty x, "${x:-\}}" should expand to "}", and that is all echo should see.

To unsubscribe from this list: send the line "unsubscribe dash" in
the body of a message to majordomo@xxxxxxxxxxxxxxx
