Shell script that finds a free TCP port, runs the Python built-in HTTP file server on that port, and then opens a new Google Chrome tab displaying the site's root directory

simplehttpserver.sh

#!/bin/bash                                                                     
#
# To use: cd to a directory you want to browse, and run this script.
#
# This lets you skip finding a free TCP port on your system and
# running SimpleHTTPServer on that port and pointing your browser there.
# Instead, we ask the SimpleHTTPServer to run at whichever free port the
# operating system would like to assign, we watch its output to see what
# port was in fact assigned, and then we open a new tab in the browser
# (in this case, Google Chrome) automatically.

Argh, *would. I can't spell.
