atomic_write

atomic_write(file_name, temp_dir = Dir.tmpdir)
Class Public methods

Write to a file atomically. Useful for situations where you don't want other processes or threads to see half-written files.

File.atomic_write('important.file') do |file|
  file.write('hello')
end

If your temp directory is not on the same filesystem as the file you're trying to write, you can provide a different temporary directory.

File.atomic_write('/data/something.important', '/data/tmp') do |file|
  file.write('hello')
end
