I'm trying to run something like:
sudo dhclient $wifi || otherFunction
Problem is when dhclient fails it just hangs instead of throwing an error.
How can I re-write the above so dhclient is killed and otherFunction gets called if dhclient doesn't finish in 60 seconds?
bash timeout

Your timeout tag gives it all away:
sudo timeout 60 dhclient $wifi || otherFunction
An example:
sudo timeout 3 sleep 5 || echo finished early
This uses the timeout utility provided by the GNU coreutils package on Linux.

Use the timeout packed as gtimeout with the coreutils port in brew:
brew install coreutils
gtimeout --help
That'll work with /usr/local/bin in your PATH. If you want to use timeout as originally named, add /usr/local/opt/coreutils/libexec/gnubin to your PATH.
