- # Summary: Set or show the global Ruby version
- #
- # Usage: rbenv global <version>
- #
- # Sets the global Ruby version. You can override the global version at
- # any time by setting a directory-specific version with `rbenv local'
- # or by setting the `RBENV_VERSION' environment variable.
- #
- # <version> should be a string matching a Ruby version known to rbenv.
- # The special version string `system' will use your default system Ruby.
- # Run `rbenv versions' for a list of available Ruby versions.
