Sets the default Ruby version. You can override the default at any time

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

setting the RBENV_VERSION environment variable.

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 default Ruby version

RBENV_VERSION environment variable.
