[TUHS] Use of "{}" in the Shell?

[Cameron Míċeál Tyre via TUHS]

Using Peter's guidance, I tried the original command discussed, in Bash on my Macbook Air, and it worked.

{ exit 1; }

The result: https://ibb.co/xq20BMvT

Side note: I also tried on Bash on Debian sandboxed on GrapheneOS and the result was the same.

Best wishes,

Cameron
