Some useful rbenv commands are:
commands List all commands
rehash Rehash rbenv shims, use after installing binaries
set-default Set global default Ruby
set-local Set local directory default Ruby
version Show Ruby version being used
versions List Ruby versions known by rbenv
rehash Rehash rbenv shims (run this after installing binaries)
set-default Set the default Ruby version
set-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 a quick guide to rbenv, see: https://gist.github.com/1120938"

set-default) echo "usage: rbenv set-default <version>
Sets the global default Ruby.
Sets the default Ruby version. You can override the default at any time
by setting a directory-specific version with \`rbenv set-default' or by
setting the RBENV_VERSION environment variable.
$(print_set_version)"
;;
set-local) echo "usage: rbenv set-local <version>
Sets the local directory default Ruby, by writing the version to a file
named '.rbenv-version'. rbenv will search for this file up the directory
tree from the current working directory each time its shims are executed,
so this default will affect subdirectories.
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 set-default', or the version specified in the
RBENV_VERSION environment variable.
