@nik Right! That’s the technically-accurate explanation. But I think many people will write a script *thinking* they’re just creating a regular old variable, not realizing they’re stepping on a landmine of good intentions

@Cykelero The same could happen with any variable if it conflicts with a global variable. If you use variable USER, you might also not realize that it already contains a value. And the value of PWD also sometimes changes "unexpectedly".
