Problem:
You are running a Chromium Kiosk e.g. on a Raspberry Pi using a command like
chromium-browser --noerrdialogs --disable-infobars --disk-cache-dir=/dev/null --disk-cache-size=1 --kiosk http://localhost
e.g. in /etc/xdg/openbox/autostart, but you don’t know how to manuy reload the Kiosk e.g. after you have changed the underlying website
Solution:
In /etc/xdg/openbox/autostart or wherever your chromium-browser command is, enclose it in
while true ; do [CHROMIUM COMMAND] ; sleep 1 ; done
The complete command would look like this, for example:
while true ; do chromium-browser --noerrdialogs --disable-infobars --disk-cache-dir=/dev/null --disk-cache-size=1 --kiosk http://localhost ; sleep 1 ; done
Now, to manually reload Chromium, all you have to do is to kill the process using
killall /usr/lib/chromium-browser/chromium-browser-v7
This will kill the Chromium process and the while loop will automatically restart it after one second.
In case you see an error message like
/usr/lib/chromium-browser/chromium-browser-v7: No such file or directory
you need to find out which executable is used for Chromium in order to pass that to killall. To find out the name of the executable, use
ps a | grep -i chromium
and look for a string similar to /usr/lib/chromium-browser/chromium-browser-v7.
