Unix Recovery Legend
Unix Recovery Legend This classic article from Mario Wolczko first appeared on Usenet in 1986. Have you ever left your terminal logged in, only to find when you came back to it that a (supposed) friend had typed "rm -rf ~/*" and was hovering over the keyboard with threats along the lines of "lend me a fiver 'til Thursday, or I hit return"? Undoubtedly the person in question would not have had the
Unix is not an acceptable Unix | Affording Play
The Unix command line is full of surprises. For instance: did you know that the OS X version of the ls tool, most frequently used to get a list of the files in the current working directory, recognizes no fewer than 38 different flags? I didn’t, so I tweeted about it. I got a couple of replies, one of which got me wondering: was Unix itself really to blame? @msimoni @maxkreminski Unfortunately, th

If you’re migrating from Linux, you’ll find many familiar commands work the way you expect.

Why Puppet, Chef, Ansible aren't good enough | Hacker News
A thing that this article is hinting at that I think might be more fundamental to making good automation principles: idempotency.Most of unix's standard set of tools (both the /bin programs and the standard C libraries) are written to make changes to state - but automation tools need to assure that you reach a certain state. Take "rm" as a trivial example - when I say `rm foo.txt`, I want the file
