I was working on a Vagrant VM and I needed to refresh the configuration because I needed another package installed. Normally, I would just perform a vagrant halt and then a vagrant up so it would install the missing packaged but I mistyped 'halt' and I got the help screen. I noticed there was an option for vagrant reload which as it turns out performs basically the same process and halt and then up.

It may not be a great tip but it has saved me a little typing.
