How do I find a list of Homebrew's installable packages?

Question

Recently I installed Brew. How can I retrieve a list of available brew packages to install?

Answer 1

From the man page:

search, -S text|/text/
Perform a substring search of formula names for text. If text is surrounded with slashes,
then it is interpreted as a regular expression. If no search term is given,
all available formula are displayed.

For your purposes, brew search will suffice.
