I would like to pass the hostname of a Raspberry Pi to Chromium in ~/.config/lxsession/LXDE-pi/autostart
The relevant parts of the command are:
@chromium-browser --incognito --kiosk https://www.example.com?pi=`hostname`
I tried using several different syntaxes to either execute hostname or read the $HOSTNAME environment variable, no luck.
Found the answer here: https://wiki.lxde.org/en/LXSession
Notice that lines are split on space characters, but no form of escaping or quoting is supported, nor are multi-line commands. So if you need, e.g., a command with a space in one of its arguments, put it in a shell script and invoke the shell script from the autostart file.
Switched to call a shell script which invoked the browser.
