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.

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
2011-08-18 19:32:33 +00:00
file is found in the tree, rbenv will use the global Ruby version
specified with \`rbenv global', or the version specified in the
2011-08-10 14:23:43 +00:00
RBENV_VERSION environment variable.
