[Attempt This Online!](https://ato.pxeger.com/run?1=m724qjhjc7SSrm5qRUlqXkpqim56Tn6SUuyCpaUlaboWK-xUHLhs4lQMIdylNjY2KvYQ9upoAx1DIDTTMYepBgA)

Outputs via exit code: `0` for not all the same; `1` for all the same

- `>$@`: create a file named for each element in the input
  - effectively deduplicates because you can only have one file with a given name
- `<^$1`: try to find a file with any name other than the first input. If there were at least two distinct inputs, this will succeed and return `0`, otherwise it will fail with status `1`
