Fixed same error issue #1.

Get error in sh (dash) for Ubuntu 13.10. The message:

  Error "/etc/init.d/hubic: 63: /etc/init.d/hubic: [[: not found"

Fixed like issue #1.
Fixed error when try use substring expansion in dash.

See https://wiki.ubuntu.com/DashAsBinSh#A.24.7Bfoo:3.5B:1.5D.7D for more
info. The message:

  /etc/init.d/hubic: 63: /etc/init.d/hubic: Bad substitution
