A wrapper over Streamly.System.Command module (from streamly-process package) to use sh as an interpreter for command strings. This package just adds sh -c to a command to run it using shell. We can use Streamly.System.Command directly instead. That we could use any shell e.g. bash -c.

This is not part of the streamly-process package because this is POSIX only and streamly-process is portable.
