Oil shell requires osh to run. That means that you can't run Oil scripts on systems that only have Bash installed.

Osh is stricter than bash. Anything written to osh should run in bash with no issues whatsoever.

Ysh implements new, non-compatible syntax and semantics.

Osh and ysh are two different shell languages from the Oils for UNIX project. The release build generates a single binary, oils-for-unix, and installation creates two symlinks for the two different shell personalities, similar to how the bash binary will behave in its POSIX-compliant mode when it is invoked as sh.

There is no "Oil shell" now, at least not without ambiguity.
