How to manually trigger fsync()?

  • 772

I've used libeatmydata to quickly perform apt-get update. Now I want to run standard fsync to make sure that everything is written to disk. How can I do it? Preferably a small script / binary, and for bonus points fsync for real even when libeatmydata is pre-loaded
