There are two problems here. The first one is that file_names[build_number] = version will return the right hand side expression, not the new value of the string, so you will be passing a "5" to the rename method, not "engine.5". The second is that by calling []= on file_names you are changing the object referenced by file_names, not making a new one, so you are passing "engine.5" as the first argument to rename. Try this instead: # Rename file replacing build number with version number new_name = file_names.dup new_name[build_number] = version_number File.rename(file_names, new_name) Also, when you change things to receive multiple file names as arguments to your script, you should probably change this line: file_names = ARGV.dup.to_s because that will join all the file names into a single string, which is not what you want, I think.
