Chrome on CL. Again

General Discussion

Some time ago, I stopped sharing scripts due to time constraints maintaining them. This one installs Google Chrome the first time, otherwise updates on subsequent use. I run it periodically. At this moment, Google Chrome is current on my system.

$ ~/bin/upd-chrome-stable 
Google Chrome stable 117.0.5938.149 (current)

upd-chrome-stable - Installer/updater combo
