Here is an example:

$ hb-shape NotoNaskhArabic-Regular.ttf --text=ب
[uni0628=0+1581]

$ hb-shape NotoNaskhArabic-Regular.ttf --text=ب --text-before=ب
[uni0628.fina=0+1673]

$ hb-shape NotoNaskhArabic-Regular.ttf --text=ب --text-after=ب
[uni0628.init=0+564]

$ hb-shape NotoNaskhArabic-Regular.ttf --text=ب --text-before=ب --text-after=ب
[uni0628.medi=0+599]
