shudder I had almost forgot.

:raises hand

At my mid 90s Unix shop, everyone had to use someone’s script which in turn called sccs. I don’t recall what it did, but I remember being annoyed that someone’s attempt to save keystrokes meant I had to debug alpha-quality script code before the sccs man page was relevant.

Adding -x to the shebang line was the only way to figure out what was really going on.
