Pass serial number when running chromium through command line

Question

I'm looking for a way to pass in the Raspberry Pi serial number to Chromium when running from the command line.

chromium-browser --incognito --noerrdialogs http://url.com?sn={serial}

Is this possible?

Answer 1

2020-02-07 answer:
You can get the serial number with:

rpi ~$ cat /sys/firmware/devicetree/base/serial-number
10000000cd0297b1

So the command to call chromium on the command line with serial number resulted in:

rpi ~$ chromium-browser --incognito --noerrdialogs http://url.com?sn=$(cat /sys/firmware/devicetree/base/serial-number)

Answer 2

here is a related question.

Briefly, you could read the file /proc/cpuinfo which would produce a listing like so

#cat /proc/cpuinfo

The last line should give you what you need.

you could use a

• python script to read the serial number (as described in the link) and launch the chromium browser with the right argument using subprocess module (the linked question's answers have such examples)

• if you commandline savvy awk would give you a one liner
