In this section, a link is provided to Wikipedia article on the shebang. The link has an extra bracket at the end, which misdirects. The link instead should be https://en.wikipedia.org/wiki/Shebang_(Unix).
This is due to there being brackets in the URL, only one of which is escaped in the notebook. The markdown should be:
[hashbang](https://en.wikipedia.org/wiki/Shebang_%28Unix%29)
