+==== Checking Raspberry Pi hardware revision from CLI ====
+<code>grep Revision /proc/cpuinfo</code>
+You can look up Raspberry Pi revision codes [[https://www.raspberrypi.org/documentation/hardware/raspberrypi/revision-codes/README.md|here]].
+==== Finding a newly booted Raspberry Pi configured by DHCP ====
+This script will find any devices on your network that have been configured by DHCP and have an ARP record.
+<code>
+#!/bin/bash
+echo "The following Raspberry Pi 4 devices have been found:"
+arp -a | grep dc:a6
+# add MAC for other models...
+echo "The following Raspberry Pi 2/3 devices have been found:"
+arp -na | grep -i "b8:27:eb"
+</code>
+==== Mounting and modifying a Raspberry Pi image file ====
+This will result in mounting a partition contained within a Pi image file at /tmp/image-part
+<code>
+file ubuntu-20.04.1-preinstalled-server-arm64+raspi.img
+# find the startsector of the partition you wish to mount (in this example 526336)
+sudo mount -o offset=$[512*526336] ubuntu-20.04.1-preinstalled-server-arm64+raspi.img /tmp/image-part
