s6-frontend-helper-echo is a small utility to echo arguments to stdout. It is not meant to be called directly, although nothing bad will happen if you do. It is used in command lines crafted by s6 live status due to unreliable and inconsistent handling of options and dash arguments in the various POSIX echo implementations.
s6-frontend-helper-echo is basically a copy of s6-echo and behaves exactly the same. The program has been included in s6-frontend in order to avoid a dependency to s6-portable-utils.
