README

This script updates to Chromium nightly. You can run it manually, but I run it using cron.

If you run it using cron remember that it _will quit_ your running Chromium so make sure you have it set to save tabs if you want them.

In order to install it with cron run:

crontab -e

Add the line:

0       0       *       *       *       bash /Users/croucher/bin/chromium-nightly.sh

I keep my script in ~/bin/ but you should update to the appropriate command.

You can also alter the first two columns to reflect when you want to update. Mine is set to 0 hours, 0 minutes (midnight) but you can set any time on a 24 hour clock.
