ID(1)

💅 ID(1) — the id girlie's guide

okay so bestie, welcome to id, from the General Commands Manual section. this is literally the page that tells you who you are (in a uid/gid way, not a spiritual way 💀). let's get into it ✨

---

🌸 NAME 🌸

id — prints user and group info for each USER you hand it, or (when you don't pass a USER at all) for the current user. that's it, that's the vibe 🫶

---

🎀 SYNOPSIS 🎀

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

---

🦋 DESCRIPTION 🦋

Print user and group information for each specified USER, or (when USER is omitted) for the current user. no cap, that's the whole thing 💖

---

✨ OPTIONS ✨

• -a, --ignore — ignore this one, it's just there for compatibility with other versions. it's giving "i'm just here so i don't get fined" 🙈
• -A — display the process audit user ID and other process audit properties — but heads up, this one requires privilege, and it's not available on Linux. so if you're on Linux, this is a no 🚫
• -u, --user — display only the effective user ID, as a number. just the digits, nothing else 🔢
• -g, --group — display only the effective group ID, as a number
• -G, --groups — display only the different group IDs, as white-space separated numbers, in no particular order. like a little group-chat of numbers fr fr 💬
• -p — make the output human-readable. each display goes on its own separate line 🧚
• -n, --name — display the name of the user or group ID instead of the number, for the -G, -g and -u options. and if any of the ID numbers can't be mapped into names? the number gets displayed as usual, no biggie 💅
• -P — display the id as a password file entry
• -r, --real — display the real ID instead of the effective ID, for the -G, -g and -u options. real vs effective, bestie, know the difference 🔥
• -z, --zero — delimit entries with NUL characters, not whitespace. and nope, this one is not permitted in default format ⚠️
• -Z, --context — print only the security context of the process — (not enabled) 🙃
• -h, --help — print help
• -V, --version — print version
• [USER] — the user you're asking about, iconically listed right here with the options 👑

👑 EXTRA 👑

so the id utility displays the user and group names and numeric IDs — of the calling process — to standard output. if the real and effective IDs are different, both get displayed; otherwise only the real ID shows up. it's giving main character energy but only when it needs to 🦋

and if you specify a user (by login name or user ID), then the user and group IDs of that user get displayed instead. in that case, the real and effective IDs are assumed to be the same. periodt 💜
