Ruby latest stable (v2_5_5) - 0 notes - Class: FileUtils

install(src, dest, mode: nil, owner: nil, group: nil, preserve: nil, noop: nil, verbose: nil) public

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 'ruby', '/usr/local/bin/ruby', :mode => 0755, :verbose => true
FileUtils.install 'lib.rb', '/usr/local/lib/ruby/site_ruby', :verbose => true
