Some useful rbenv commands are:
commands List all rbenv commands
rehash Rehash rbenv shims (run this after installing binaries)
global Set or show the global Ruby version
local Set or show the local directory-specific Ruby version
shell Set or show the shell-specific Ruby version
version Show the current Ruby version
versions List all Ruby versions known by rbenv
which Show the full path for the given Ruby command
whence List all Ruby versions with the given command
See 'rbenv help <command>' for information on a specific command.

global) echo "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.
$(print_set_version)"
;;
local) echo "usage: rbenv local <version>
rbenv local --unset
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 global Ruby version
specified with \`rbenv global', or the version specified in the
RBENV_VERSION environment variable.
$(print_set_version)"
;;
shell) echo "usage: rbenv shell <version>
rbenv shell --unset
Sets a shell-specific Ruby version by setting the 'RBENV_VERSION'
environment variable in your shell. This version overrides both
project-specific versions and the global version.
$(print_set_version)"
;;
versions) echo "usage: rbenv versions
rbenv versions --bare
Lists all Ruby versions known by rbenv."
;;
which) echo "usage: rbenv which <command>
Displays the full path to the binary that rbenv will execute when you
run the given command."
