My shower stall has a half inch crack. It is about 8 inches from

those are for holes, I think, not for small cracks.

How do I repair a small crack? Thanks.

Uh, 1/2" x 8" is not a small crack. It is a failure.
Bite the bullet, get it replaced, and get it over with. A crack in the
field like that means insufficient support below. Not to mention, it has
likely been leaking for awhile, and you have subfloor problems to deal
with. Is there finish space below? Can you get to the bottom side of
shower and look for traces of a leak?
