I thought to learn something useful for programing (debugging, program runtime analysis, etc.). But instead the article is just about the generic commands cat, sort, grep, cut, sed, uniq, find and less. It is not really development related.
I disagree. They may not be obviously related to coding, though they'll probably end up being useful at some point anyway... But they're definitely useful for working with logs, working with datasets, working with config files, and a host of other development-related tasks. Just yesterday I was on a Windows machine and dearly felt the loss of sed and uniq. I have a task lined up for today to either find Windows alternatives or install msys.
You and I do, but surely you know a web dev or two that struggles to read log files meaningfully or doesn't know how to grep their html source for something?
Send the article along, it's not always about you...
