|
global Set or show the global Ruby version
|

local Set or show the local directory-specific Ruby version
|
|
version Show the current Ruby version
|
|
versions List all Ruby versions known by rbenv

Sets the global Ruby version. You can override the global version at

any time by setting a directory-specific version with \`rbenv local'

Sets the local directory-specific Ruby version by writing the version

When you run a Ruby command, rbenv will look for an '.rbenv-version'

file in the current directory and each parent directory. If no such

file is found in the tree, rbenv will use the global Ruby version

specified with \`rbenv global', or the version specified in the

RBENV_VERSION environment variable.
