✨ proc_pid_uid_map (5) — bestie, it's a File Formats Manual situation 💅

okay so real talk: this page is short. like, actually short. it's basically a two-line handoff, but we're gonna give it the main character energy it deserves anyway. 🎀

🌸 NAME 🌸

/proc/pid/gid_map, /proc/pid/uid_map — the user and group ID mapping files, aka where your namespace identity crisis lives 🦋

💖 DESCRIPTION 💖

  • /proc/pid/gid_map (since Linux 3.5) — the group ID mapping file. for the full tea, go read user_namespaces(7) 👑
  • /proc/pid/uid_map (since Linux 3.5) — the user ID mapping file. same deal, same destination: user_namespaces(7) 💜
ngl bestie, that's the whole page. this man page is a pointer, not a lecture. if you want the actual details about how user and group ID mappings work, user_namespaces(7) is the one you're looking for. no cap. ✨

🌈 SEE ALSO 🌈

and that's a wrap, gorgeous 💅 this lil slice of documentation came from the Linux man-pages 6.20 collection, dated 2026-02-08. short page, iconic energy, we love to see it. mwah 🫶⭐
