rename a json file in ruby

To rename a JSON file in Ruby, you can use the built-in File class and its rename method. Here's an example:

main.rb
File.rename("old_filename.json", "new_filename.json")
54 chars
2 lines

Note that this will rename the file in the same directory. If you need to rename a file in a different directory or with a different path, you'll need to include the full path in the file names:

main.rb
File.rename("/path/to/old_filename.json", "/path/to/new_filename.json")
72 chars
2 lines

Make sure to handle potential errors that may arise from file operations, such as the file not existing or the new file name already being taken.
