It does actually lock the file but on Ubuntu the code uses flock()
internally, these locks are advisory which means there is no actual requirement to follow the locking.
Just execute the code from your console in 2 separate consoles and you will notice the locks but as far as I know there is no standard way to force locking on Ubuntu without changing your mounts to mandatory locking (with -o mand
). But even these are known to be buggy unfortunately.
