🌸 NAME 🌸

/proc/sys/abi/ — application binary information ✨

---

🦋 DESCRIPTION 🦋

So. /proc/sys/abi/ has been a thing since Linux 2.4.10, which is giving vintage, it's giving legacy, it's giving "been here longer than you" 💅

This directory may contain files with application binary information. That's it. That's the description. Short queen, minimal effort, still iconic 🎀

And if you want the actual tea — the full lore, the whole story — you go look at the Linux kernel source file Documentation/sysctl/abi.rst for more information. 🙈

heads up bestie: if you're on a kernel older than Linux 5.3, that file is called Documentation/sysctl/abi.txt instead. same energy, different extension 🫶
