# 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.
