Ian Downes commented on MESOS-1424:
-----------------------------------
Specifically, man 1 echo (for /bin/echo) includes this statement:
{noformat}
Applications aiming for maximum portability are strongly encouraged to use
printf(1) to suppress the newline character.
{noformat}
> Mesos tests should not rely on echo

> Key: MESOS-1424
> URL: https://issues.apache.org/jira/browse/MESOS-1424
> Project: Mesos
> Issue Type: Improvement
> Components: test
> Reporter: Till Toenshoff
> Priority: Minor
> Labels: cleanup, easyfix, osx, tests
>
> Triggered by MESOS-1413 I would like to propose changing our tests to not
> rely on {{echo}} but to use {{printf}} instead.
> This seems to be useful as {{echo}} is introducing an extra linefeed after
> the supplied string whereas {{printf}} does not. The {{-n}} switch preventing
> that extra linefeed is unfortunately not portable - it is not supported by
> the builtin {{echo}} of the BSD / OSX {{/bin/sh}}.
