Basic commands for the VI editor

When you need to edit files on an ESXi host directly or on a Linux-host, such as the vCenter appliance, then it is a useful skill to be able to use the VI-editor. In this article I describe the absolute basics you need to know.

The easiest way to open a file with the VI-editor is to start the program with the filename of the file to edit as a parameter. Such as this:

vi /etc/udev/rules.d/70-persistent-net-rules

Using a Power Bank as a UPS for your Raspberry Pi

I am running a Raspberry Pi as a USB-server for my virtual environment (see this article). That device is plugged into my server's UPS so it will keep running when there is a power failure. But when you use your Raspberry Pi for other purposes, for example in a stand-alone scenario with sensors or switches you also might want it to keep running when there is a power failure.
