## Intermediate Sed Usage

If you’ve been using Linux for any small length of time, you’ve likely used sed before. Most of the time, you’ve seen it in the form of sed "s/find/replace/g", so you simply go to it whenever there’s a replacement you want to do.

But sed stands for stream editor, and as a tool it can do more than just find and replace.

For all my undergrad, my laptop was a refurb’d EliteBook 2540p. It was released in 2010 around the $1000 mark, and I picked it up in the summer of 2014 for$300. It was a little 12-inch thing, came with Windows 7 and no bloatware to speak of. I loved that thing, despite the overheating, the weight, the first-gen Intel Core series chip, the pathetic battery life, and the overheating.
