> The "sh" command in grunt is very sensitive to the behavior of exec. It
> requires that you provide an executable filename as the first argument, and
> those are sort of up for interpretation from platform to platform. For this
> to easily handle batch scripts, built-in commands, and executables with one
> semantic, it should spin up an intermediate command-shell. This would
> translate "sh <command>" into "exec("sh" ["-c", <command>])". This helps to
> smooth out some of the operating system differences between Windows and
> Linux, and also improves usability of grunt as a whole.
