✨ NAME ✨

who — show who is logged on 🫶

🌸 SYNOPSIS 🌸

who [OPTION]... [ FILE | ARG1 ARG2 ]

💅 DESCRIPTION 💅

It prints info about the users who are currently logged in. That's it. That's the whole vibe. stalker-era but make it sysadmin 🔥

🎀 OPTIONS 🎀

  • -a, --all — literally the whole buffet: same as -b -d --login -p -r -t -T -u ✨
  • -b, --boot — when the system last booted up (its little wake-up moment 💫)
  • -d, --dead — prints dead processes 🪦 (not me calling them dead, that's the flag's name)
  • -H, --heading — prints a line of column headings, so you actually know what you're looking at 🎯
  • -l, --login — prints the system login processes
  • --lookup — tries to canonicalize hostnames via DNS 🌐
  • -m — only the hostname and user tied to standard input
  • -p, --process — prints the active processes spawned by init 👑
  • -q, --count — all the login names plus how many users are logged on 🔢
  • -r, --runlevel — prints the current runlevel
  • -s, --short — prints only name, line, and time. This is the default, so if you do nothing, this is what you get 🍓
  • -t, --time — prints the last system clock change ⏰
  • -T, -w, --mesg — adds the user's message status as +, - or ? 💬
  • -u, --users — lists users logged in, idle time included 😴
  • --message — same as -T
  • --writable — same as -T
  • --help — display this help and exit 🫶
  • --version — output version information and exit

If FILE isn't specified, it uses /var/run/utmp. Using /var/log/wtmp as FILE is common. And if you pass ARG1 ARG2, then -m is presumed — 'am i' or 'mom likes' are the usual ones 😭 iconic behavior fr fr
