I've been meaning to share this with you for some time. I've really enjoyed Mike's eight-part School of Linux series (8th installment in LXF 148). I found each article to be a nice, bite-sized nugget of carefully written Linux goodness, with each article and the whole series having a logical pedagogy. From previous tutorials and answers in the magazine, I found that I was familiar with most of the commands covered but I couldn't make use of them. These articles have helped me learn how to use the commands, they started at the right level and took me further into the subject, filling in the holes in my knowledge.
I've often struggled with the previous Bash tutorials, as I didn't understand the aim of them or found subject covered to be quite esoteric. With Mike's series, I feel like I've learned about Linux via Bash and the commands used, rather than just learned about Bash and the commands in isolation. I heartily recommend to everyone to read through these if you haven't done so already. It's also great knowledge to have, as Linux is what unites every distro, so one needn't be reliant on having a particular distro's admin tools available when one is away from one's own systems.
Well done, Mike.
