Eller varför inte en Raspberry Pi för mätningar? Linux är viktigare och större än någonsin. Det finns överallt. På servrarna som tillhandahåller många av de webbsidor du surfar på. Det finns i stora beräkningskluster, telefoner, bilar och underhållningssystem. I början av boken får du grundläggande kunskaper om hur du arbetar med Linux. Här lär du dig bland annat hur Linux är uppbyggt, användbara kommandon, filsystemets uppbyggnad och hur du redigerar filer i både Nano och Vi. Därefter lär du dig att skapa nya användare och grupper i systemet. Du lär dig också hur du sätter filrättigheter i Linux. Mot mitten av boken lär du dig mer avancerade ämnen, så som textbearbetning, att skriva egna skalskript, administrera tjänster, processhantering, nätverkskonfiguration och mycket mer. Boken fungerar för de flesta Linuxutgåvor. Men bland annat kapitlen om pakethantering och nätverkskonfiguration har skrivits speciellt för Red Hat, CentOS, Fedora, Debian och Ubuntu. Till varje kapitel finns det övningsuppgifter så att du själv kan träna på det du lärt dig. En del av övningsuppgifterna går utanför boken, och du måste då själv leta upp rätt kommandon i den inbyggda manualen.

Have you suffered from a botched migration of thousands of users to a new service? Does your company rely on a computer that, if it died, can’t be rebuilt? Is your network a fragile mess that breaks any time you try to improve it? Is there a periodic “hell month” that happens twice a year? Twelve times a year? Do you find out about problems when your users call you to complain? Does your corporate “Change Review Board” terrify you? Does each division of your company have their own broken way of doing things? Do you fear that automation will replace you, or break more than it fixes? Are you underpaid and overworked?

No vague “management speak” or empty platitudes. This comprehensive guide provides real solutions that prevent these problems and more!

Learn PowerShell in a Month of Lunches: Covers Windows, Linux, and macOS is a task-focused tutorial for administering Linux and macOS systems using Microsoft PowerShell. Adapted by PowerShell team members Travis Plunk and Tyler Leonhardt from the bestselling Learn Windows PowerShell in a Month of Lunches by community legends Don Jones and Jeffrey Hicks, it features Linux-based examples covering core language features and admin tasks. Designed for busy IT professionals, this innovative guide will take you from the basics to PowerShell proficiency through 25 tutorials you can do in your lunch break.

about the technologyThe PowerShell scripting language and administrative shell was initially created for Windows, providing a high-quality command-line interface and awesome automation features. As part of Microsoft's ongoing strategy to support non-Windows platforms with its Azure cloud service and .NET Core framework, PowerShell now runs on Linux and macOS. Like Bash, PowerShell can execute and script nearly any aspect of Linux, so you can easily manage repetitive daily tasks, servers, Cloud resources, Continuous Integration pipelines, and more. Because PowerShell is a full-featured programming language, however, it provides capability well beyond traditional shell scripting languages, such as the ability to treat OS components as objects.

about the bookLearn PowerShell in a Month of Lunches: Covers Windows, Linux, and macOS is a user-friendly tutorial to managing Linux and macOS systems with PowerShell. It's based on the bestselling Learn Windows PowerShell in a Month of Lunches, which has introduced PowerShell to nearly 100,000 readers. You'll learn how PowerShell shapes up to Bash or Python scripting as you write and run simple scripts that automate boring daily tasks. As you progress through the book, you'll use PowerShell to write Continuous Integration Pipelines and manage cloud-based servers. Just set aside one hour a day for a month, and you'll be automating tasks faster than you ever thought possible!

Discover how to apply software engineering patterns to develop more robust firmware faster than traditional embedded development approaches. In the authors’ experience, traditional embedded software projects tend towards monolithic applications that are optimized for their target hardware platforms. This leads to software that is fragile in terms of extensibility and difficult to test without fully integrated software and hardware. Patterns in the Machine focuses on creating loosely coupled implementations that embrace both change and testability.This book illustrates how implementing continuous integration, automated unit testing, platform-independent code, and other best practices that are not typically implemented in the embedded systems world is not just feasible but also practical for today’s embedded projects.After reading this book, you will have a better idea of how to structure your embedded software projects. You will recognize that while writing unit tests, creating simulators, and implementing continuous integration requires time and effort up front, you will be amply rewarded at the end of the project in terms of quality, adaptability, and maintainability of your code. What You Will LearnIncorporate automated unit testing into an embedded projectDesign and build functional simulators for an embedded projectWrite production-quality software when hardware is not availableUse the Data Model architectural pattern to create a highly decoupled design and implementationUnderstand the importance of defining the software architecture before implementation starts and how to do itDiscover why documentation is essential for an embedded projectUse finite state machines in embedded projectsWho This Book Is ForMid-level or higher embedded systems (firmware) developers, technical leads, software architects, and development managers.
