This script converts a Google Chrome rpm package into standalone (portable) format. Usage example:
sh standalone-google-chrome.sh google-chrome-stable_current_x86_64.rpm
When the script is done you will have a suitably version named directory. You can run the copy of Google Chrome stored within it as follows:
google-chrome-stable-41.0.2272.118-1/run &
Copy or move the directory wherever you like.
