Some useful rbenv commands are:
commands List all commands
rehash Rehash rbenv shims (run this after installing binaries)
default Set the default Ruby version
local Set a local directory-specific Ruby version
version Show the current Ruby version
versions List all Ruby versions known by rbenv
See 'rbenv help <command>' for more information on a specific command.
For more information, see: https://github.com/sstephenson/rbenv#readme"

default) echo "usage: rbenv default <version>
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.
$(print_set_version)"
;;
local) echo "usage: rbenv local <version>
Sets the local directory-specific Ruby version by writing the version
name to a file named '.rbenv-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
specified with \`rbenv default', or the version specified in the
RBENV_VERSION environment variable.
