How can I delete Chromium browser history at boot up on Raspberry Pi-3?
These two commands clear chromiums cache:
rm ~/.config/google-chrome/Default/ rm ~/.cache/google-chrome
to execute this commands on boot edit your crontab file (more about cronjobs):
append this line to the end of the file:
@reboot rm ~/.config/google-chrome/Default/ && rm ~/.cache/google-chrome
@reboot executes the following commands to remove the chromium/chrome cache at each reboot of your pi but more on the reboot keyword here
Note: To use the @reboot function you have to be root
Hope I could help!
