Ruby file FAQ: How do I append text to a file in Ruby? Solution: Appending text to a file with Ruby is similar to other languages: you open the file in "append" mode, write your data, and then close the file. Here's a quick example that demonstrates how to append "Hello, world" to a file named myfile.
Are you looking for the following?
File.open(yourfile, 'w') { |file| file.write("your text") } You can use the short version:
File.write('/path/to/file', 'Some glorious content') It returns the length written; see ::write for more details and options.
To append to the file, if it already exists, use:
File.write('/path/to/file', 'Some glorious content', mode: 'a') If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
