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 |f| file.write("hello") end
