✨ ID(1) — the "who even am I" command ✨

okay bestie, so this is id from the User Commands manual, and honestly? it's giving ✨identity crisis✨ in the best possible way 💅

🌸 NAME 🌸

id — print real and effective user and group IDs 🫶

🎀 SYNOPSIS 🎀

id [OPTION]... [USER]...

💖 DESCRIPTION 💖

So like, what does it do? It prints user and group info for each USER you hand it — or, if you don't give it a USER at all, it does it for the current process. no cap, that's the whole vibe 🌈

  • -a — ignore this one, it's just there for compatibility with other versions 🙈 (yes really, it does nothing, iconic behaviour honestly)
  • -Z, --context — print only the security context of the process 🔥
  • -g, --group — print only the effective group ID 💜
  • -G, --groups — print ALL the group IDs, every single one 👑
  • -n, --name — print a name instead of a number — works with -u, -g, and -G ✨
  • -r, --real — print the real ID instead of the effective ID — also works with -u, -g, and -G 🦋
  • -u, --user — print only the effective user ID ⭐
  • -z, --zero — delimit entries with NUL characters instead of whitespace 🌸
⚠️ not permitted in default format, bestie. the command said what it said 💀
  • --help — display this help and exit 🎀
  • --version — output version information and exit 🧚

And if you pass no OPTION at all? It prints some useful set of identified information. lowkey a little treat 🍓
