Today, we bring you a collection of shortcuts, cheatsheets, commands and quick references for systems administrators working on Linux or Windows systems, databases, networks or web servers.
These days, there is so much information and so many tools that it is almost impossible to remember it all. At the same time, IT workers are expected to work with a wide range of different programs whilst responding as quickly as possible to user requests. As a result, the quality of your bookmarks, shortcuts, cheatsheets, quick guides and summary sheets are really important.
Working in IT, you sometimes need to learn how to do something quickly. There’s no time to learn about the wheres or whys. You just need results… and fast. It’s happened to all of us at one point or another, but only a few people have taken the time and effort to publish the information to make our lives easier. So, thanks to all of them for their fantastic cheatsheets!
Today, we’ve put together a collection of what we believe is the best material for systems administrators, so that you can save it, use it or bookmark it. We hope that you find it useful:
