I have been a Macintosh user for quite some time now and I have never, not once, not a single time, correctly distinguished "brew update" from "brew upgrade" on the first try
@marcoarment alias bupdate="brew update && brew upgrade"
… made this years ago and never bothered again. But I am more concerened about the amount of what is all that for and why did I install it in my machine over the years when I do that.
