💖 proc_cpuinfo(5) 💖

okay so this is proc_cpuinfo from section 5 of the manual — the File Formats Manual bestie, we're in file-formats territory, not commands. get comfy 🫶

✨ NAME ✨

/proc/cpuinfo — CPU and system architecture information 🧠✨

---

🌸 DESCRIPTION 🌸

/proc/cpuinfo

bestie. this file is literally the receipts on your CPU. 💅

It's a whole collection of CPU and system architecture dependent items, and here's the tea: for each supported architecture you get a different list. So like, don't go expecting the exact same fields everywhere — the vibe shifts depending on what arch you're on. no cap. 🦋

Two entries that show up pretty much everywhere, the iconic duo:

• processor — gives you the CPU number 👑
• bogomips — a system constant that gets calculated during kernel initialization ⭐

and that's not all — SMP machines have information for each CPU. so if you've got multiple processors, you get the whole squad listed out, one after another. main character energy per core, fr fr. 🌈

Oh and also? lscpu(1) gathers its information from this file. So yeah, when lscpu is out there looking all neat and formatted, it's lowkey just serving you a glow-up of what's already sitting right here. 💀✨
