rename a directory in ruby

To rename a directory in Ruby, you can use the FileUtils.mv method from the fileutils standard library.

Here's an example code snippet that demonstrates how to do this:

main.rb
require 'fileutils'

# specify the current directory name and the new directory name
current_dir_name = "my_existing_dir"
new_dir_name = "my_new_dir_name"

# use the FileUtils.mv method to rename the directory
FileUtils.mv(current_dir_name, new_dir_name)
255 chars
9 lines

In this example, we first require the fileutils library. Then we specify the current directory name and the new directory name as strings. Finally, we call the FileUtils.mv method and pass in the current directory name and the new directory name as arguments. This will rename the directory from the old name to the new name.
