Have also added the model from the pi

Just in addition, here's my ansible playbook (using revision 2 of your script):

- hosts: rasppis
  tasks:
          - name: Get version
            script: ../local-scripts/pi-version.sh
            register: output
            changed_when: False

          - debug:
              msg: System {{ inventory_hostname }} is {{ output.stdout_lines | first }}

$ ansible-playbook playbooks/show-raspberry-pi-version.yml | grep "is Revision"
...
    "msg": "System alarmpi-bba3 is Revision : 000e (Model B Rev 2, 512MB)"
    "msg": "System alarmpi-ab8a is Revision : a020d3 (Pi 3 Model B+, (Sony, UK), 1GBB)"
...

The output could be further processed using sed/awk/whatever. But this is sufficient for a quick view of all pi revisions. Thanks again for sharing this!

By the way, using your script (revision 3) I get line 4: warning: command substitution: ignored null byte in input. This is due to the fact that /sys/firmware/devicetree/base/model ends with a hex 0 value. Didn't know that before...

Hi, there are two duplicates with different values:

• 0015: Model A+, (Embest, China), 256MB and Model A+, (Embest, China), 512MB
• a01041: Pi 2 Model B v1.1, (Sony, UK), 1GB) and Pi 2 Model B v1.1, (Embest, China), 1GB)

which one of those is it? Also, there's a typo in the name of 000f, it reads 0009.

According to the official docs, 0015can be both 256/512 MB.

It seems one a01041 should be coded as a21041.

My proposal:

    "0015" )
        echo "Revision : 0015 (Model A+, (Embest, China), 256/512MB)" ;;
    "a01041" )
        echo "Revision : a01041 (Pi 2 Model B v1.1, (Sony, UK), 1GB)" ;;
    "a21041" )
        echo "Revision : a21041 (Pi 2 Model B v1.1, (Embest, China), 1GB)" ;;

Edit: changed revision text to a21041

My proposal:

@wopfel thanks for your comments, have updated the gist.

@mhzawadi, what about the typo in 000f?
