When I install or reinstall a formula, homebrew automatically update itself before installing the formula.
When working on a slow connection, this is annoying. How can I cancel this automatic update?

HOMEBREW_NO_AUTO_UPDATE=1 brew install <formula>
This will stop the homebrew update for this command. If you want to prevent auto update for your shell session, use:
to set it permanently, add it to your
~/.bash_profile. Note that changing this permanently is discouraged by the developers.
A better alternative may be instead to set
HOMEBREW_AUTO_UPDATE_SECSto a higher value (the default is to try and update every 60 seconds).
Add the command to
~/.bash_profile to keep the settings for different terminal sessions.
