Without Internet searching - no cheating.

What does the "sync" command line instruction do? e.g. sudo sync

First to reply correctly is crowned as Nerd-for-the-Day.

is sync actually still around?  my memory is that it flushes the disk cache to disk, but doesn't shutdown.   Not sure why anyone needs that with eisy et al.  When we ran a live multi-user system it was used in backup scripts after all users had signed out or been forced off.

I admit I had to look that one up. I have never used it before.

It sounds like a misnomer for that command. "flush" would have been a better name IMHO.
Don't forget to run "toiletpaper" just before "flush" and then "sync". :)
