Thanks to modern GUI desktop environments and applications, anyone can jump into the fray and know what they’re doing.On the rare occasions when trouble arises, you might want to know a few commands to help you out. The problem is that there are so many commands available within the realm of Linux, which makes it challenging to know which commands are the best options.
