brew info always has a exit code 0. so it's useless. brew list [email protected] &>/dev/null || brew install [email protected]; works because it returns 1 when there's nothing found.

the disadvantage of brew info <formula> is that it loads very slowly, as it has to fetch the statistics of the formula from the Internet. If you use brew list <formula> | grep "No such keg" (or something similar), the result will be displayed much faster.
