Why an introductory Linux admin, command line-oriented eBook in 2023 when GUIs are so powerful now and Windows is still the dominant desktop OS?Well, lots of reasons, but for anyone looking for a career in IT, having some Linux skills is an obvious bonus and as it's a free OS that has programmes written for it that cover almost any use anyone would want. It's a cheap way in to the IT industry for students on a budget if nothing else, as it runs on almost all hardware, but you can research what laptops or hardware like Wi-Fi cards it doesn't have in built drivers for on the web.Linux has never been so popular, as it's a very stable, truly multitasking OS, and I hope to show you some of its incredibly low overhead versatility, running as it is on my 15 year old, dual core laptop, writing this text - from basic Desktop user admin, to software installation, file system security concepts, basic programming environments for Python, C and Java, and very importantly, backups. All in 5 "days", more or less...dependent on you
