Method: FileUtils.install

Defined in:
lib/fileutils.rb

.install(src, dest, options = {}) ⇒ Object

Options: mode preserve noop verbose

If src is not same as dest, copies it and changes the permission mode to mode. If dest is a directory, destination is dest/src. This method removes destination before copy.

FileUtils.install 'lib.rb', '/usr/local/lib/ruby/site_ruby', :verbose => true
