💖 NAME 💖

okay bestie, so this page is all about /proc/pid/personality — it's literally the execution domain file, no cap ✨

🌸 DESCRIPTION 🌸

🦋 /proc/pid/personality (since Linux 2.6.28)

so like, this file is read-only and it spills the tea on your process's execution domain — the one that got set by personality(2). periodt 💅

the value shows up in hexadecimal notation, so if you were expecting cute lil decimal numbers, nope, it's giving hex energy 🔥

permission to access this file? it's governed by a ptrace access mode PTRACE_MODE_ATTACH_FSCREDS check — so go see ptrace(2) for the whole vibe check, iykyk 👑

👑 SEE ALSO 👑

this iconic little page came from the Linux man-pages 6.20 era, dated 2026-02-08, and it's officially known as proc_pid_personality(5) — slay, bye bestie 💜✨
