If you use Unix today, you can enjoy relatively long file names on more or less any filesystem that you care to name. But it wasn't always this way. Research V7 had 14-byte filenames, and the System III/System V lineage continued this restriction until it merged with BSD Unix, which had significantly increased this limit as part of moving to a new filesystem (initially called the 'Fast File System', for good reasons). You might wonder where this unusual number came from, and for that matter, wha

40 years ago today: I joined a tiny startup called Sun Microsystems. What a ride! Here’s the never-before-told story of how I arrived at Sun as employee #8! 🧵 I started out in Silicon Valley in June of 1978 working at Amdahl Corp. porting UNIX to the mainframe, a revival of the work started at Princeton in 1975. Sometime in late ’80 I moved over to Amdahl’s architecture group to work on data communications – X.25, SNA, etc. But that work wasn’t too satisfying. During the UNIX/UTS work I had b

The prominent position of the shell in the UNIX Magic poster reflects its central role in UNIX systems. The shell was (and still is) the primary interface for interacting with the kernel, serving as the workbench of the UNIX user. It is an incredibly powerful tool, allowing users to launch and coordinate processes, perform complex computations, and interface directly with the operating system. The shell is not just an interface; it is also a full programming language. Users can write scripts to

Linux and Unix are essentially two takes on the same operating system, with Linux serving as the free, open-source version. This book serves as an all-around introduction to programming for a Linux or Unix operating system, covering how to write programs on and for the Linux OS, how to work efficiently within a Unix/Linux environment, and how the underlying design and structure of the Unix OS work. The author’s friendly, conversational style reflects his more than 40 years of experience teachi

The Unix shell is over 50 years old, but it still defines how programmers use their computers. We type a few words in a terminal, and milliseconds later an ephemeral factory comes online: the Unix pipeline. Data streams through a network of simple programs working concurrently, like robots on the factory floor, executing a computational choreography we composed seconds ago. Its job done, the factory vanishes. Onto the next command. That loop built the internet, and still runs it today. The desi

[TUHS] 1972 UNIX V2 "Beta" Resurrected Hi everyone, First-time poster here. Near the end of last year, I did some forensic analysis on the DMR tapes (https://www.tuhs.org/Archive/Applications/Dennis_Tapes) and had some fun playing around with them. Warren forwarded a few of my emails to this list at the end of last year and the beginning of this year, but it was never my intention for him to be my messenger, so I'm posting here myself now. Here's an update on my work with the s1/s2 tapes - I've
