    Why should this be faster than rm -rf Commented Nov 29, 2022 at 16:55
  • If you have ~100k files in a folder, ‘rm -rf’ would take some time to complete. ‘mv folder /tmp/folder’ would take less than 3 seconds. Commented Nov 30, 2022 at 17:25
  • you are cheating. You need to consider the time to restart as well. Similarly, you could enter a cron job and claim its faster as it requires no time at all (at the moment at least) Commented Nov 30, 2022 at 21:19
  • Why downvote? It's not cheating, /tmp is just a convenient example, because it exists on all *nix platforms. You can create a TMPFS and just remount it, and it's just the same without restarting. Commented Dec 1, 2022 at 8:12
  • Because I have serious doubts that it's faster. Your benchmark does not account for the time necessary for the restart. On my system the restart is ~3 minutes - which is well above the 30s. Commented Dec 1, 2022 at 15:24
