💖 ID(1) — like, the id command bestie 💖

okay so real quick: this is id, from the User Commands manual, and it's about to tell you exactly who you are (in the Unix sense, not the existential sense, though honestly both). ✨

🌸 NAME 🌸

id — print real and effective user and group IDs 🫶

🌈 SYNOPSIS 🌈

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

✨ DESCRIPTION ✨

So basically: it prints user and group info for every USER you hand it, or — if you don't give it any USER at all — for the current process. Lowkey iconic. 💅

Heads up bestie, all the flags live right here in the description, so we're doing them all, no skipping, no cap.
  • -a — ignore it, fr. It's only there for compatibility with other versions. Main character? No, background extra. 💀
  • -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
  • -n, --name — print a name instead of a number, and it works with -u,-g,-G
  • -r, --real — print the real ID instead of the effective ID, with -u,-g,-G
  • -u, --user — print only the effective user ID
  • -z, --zero — delimit entries with NUL characters instead of whitespace; > warning: this one is not permitted in default format, okay? not allowed. periodt. 🚫
  • --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. Just a nice little grab bag of who-you-are. 🌸
