The default shell on Linux is (usually) bash. More importantly /bin/sh
is simply a link to /bin/bash.

/bin/sh on Cygwin defaults to ash, a drop-in replacement for the
Bourne Shell. /bin/sh != /bin/bash.

Make sure that if your script uses Bash-specific features, it starts
with #!/bin/bash and not with #!/bin/sh. That way it'll work anywhere.
