delete a file in ruby

To delete a file in Ruby, you can use the built-in File class and its delete method. The syntax for deleting a file is as follows:

main.rb
File.delete('file_name.txt')
29 chars
2 lines

In this example, replace 'file_name.txt' with the actual name and file extension of the file you want to delete.

If the file you want to delete is read-only, you might need to set the file's writable flag before deleting it. Here's what that looks like:

main.rb
# make the file writable
File.chmod(0666, 'file_name.txt')
# delete the file
File.delete('file_name.txt')
106 chars
5 lines

Note that the chmod method takes an integer as its first argument, which represents the file's permission mode. In this example, 0666 corresponds to the permission mode that makes the file readable and writable by everyone.
