id(1)

💖 id(1) — bestie, let's find out who you even ARE 💖

okay so real talk, this is the id page from the General Commands Manual, and it's genuinely one of the most useful little commands in your whole toolkit. it's giving "who am i, really" energy, but for your user and group IDs. no cap.

✨ NAME ✨

id — Print user and group information for each specified USER, or (when USER omitted) for the current user.

like literally it just tells you who the process thinks it is. iconic behaviour honestly 🫶

🌸 SYNOPSIS 🌸

id [-a|--ignore] [-A ] [-u|--user] [-g|--group] [-G|--groups] [-p ]
[-n|--name] [-P ] [-r|--real] [-z|--zero] [-Z|--context] [-h|--help]
[-V|--version] [USER]

she's got a LOT of flags bestie, don't panic, we're going through every single one 💅

🦋 DESCRIPTION 🦋

Print user and group information for each specified USER, or (when USER omitted) for the current user.

that's it. that's the whole vibe. you ask, she answers, you move on with your day ✨

👑 OPTIONS 👑

• -a, --ignore — ignore, for compatibility with other versions
• -A — Display the process audit user ID and other process audit properties, which requires privilege (not available on Linux).
• -u, --user — Display only the effective user ID as a number.
• -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.
• -p — Make the output human-readable. Each display is on a separate line.
• -n, --name — Display the name of the user or group ID for the -G, -g and -u options instead of the number. If any of the ID numbers cannot be mapped into names, the number will be displayed as usual.
• -P — Display the id as a password file entry.
• -r, --real — Display the real ID for the -G, -g and -u options instead of the effective ID.
• -z, --zero — delimit entries with NUL characters, not whitespace; not permitted in default format
• -Z, --context — print only the security context of the process
• -h, --help — Print help
• -V, --version — Print version
• [USER]

heads up bestie 💀 -z is not permitted in default format. she's strict about that one. and -A needs privilege and is not available on Linux, so don't come for her when it doesn't work.

🌈 EXTRA 🌈

The id utility displays the user and group names and numeric IDs, of the calling process, to the standard output. If the real and effective IDs are different, both are displayed, otherwise only the real ID is displayed.

If a user (login name or user ID) is specified, the user and group IDs of that user are displayed. In this case, the real and effective IDs are assumed to be the same.

so basically: no USER = she's talking about you. USER given = she's talking about them, and she just assumes real == effective because why would she assume otherwise, that's rude 🎀
