About me I am a Computer Science M. Sc. student (they/them). My research interests are knowledge representation and processing of math, and lately also programming language theory. I contribute to the MMT project (UniFormal/MMT on GitHub), a larger research software written in Scala which lets you formalize a broad range of formal knowledge: math, logic, type theory, and foundations. MMT and many of its algorithms are foundation-independent: with bare MMT, you don't even have natural numbers, let alone functions. The beauty is versatility; the challenge generality. For more info and publications, see my academic website and personal website. More hobby-wise, I am dabbling in the Coq Proof Assistant and, e.g., formalized my own flavor of an ontology language and a lambda calculus with de Bruijn indices. Programming-wise, I also fancy the latest TypeScript/ECMAScript. And I like writing/autogenerating syntax highlighters that succeed on over 15k lines of code. Feel free to reach out (by posting an issue here)! I always love hearing and chatting about cool things.

All of us probably know .bat for Batch files.

But what is the file extension for PowerShell 3 scripts?

I found .ps1 and some other endings but they're only for version 1.

Update for 2014: This is still relevant now with Powershell 4. I think the 1 was really just to distinguish it from .ps (PostScript) files, but it made for a lot of confusion!

always wanted to know what the 1 meant. Guess it's not related to the version but pretty sure the had something to do with it when they created the file type for PS 1.0.

@Geddon I once read somewhere that they chose ps1 to avoid conflicts with ps, which was already in use by Adobe Photoshop. Other sources say that versioning had been indeed the reason to call it ps1, but they dropped this idea when introducing PS 2 (official source).

This is a weird extension for sure. Why not .psh then?!

Just tried it out and it looks like .psh is used for HSLS sources in Visual Studio. Given that Microsoft develops VS, it seems likely that they went with .ps1 also because of that reason.

Why it is ps1, and not just ps?

ps is a longstanding file extension for postscript files.
