πŸ’– who@(1) β€” the manual page, but make it make sense

okay bestie, so this is who@ from the General Commands Manual, and honestly? she's a tiny icon. one job, does it, no drama. let's go 🫢


✨ NAME ✨

who@ β€” prints the list of active users on a remote host. that's it. that's the whole personality. πŸ‘‘


🌸 SYNOPSIS 🌸

who@ [ host ]

like... one optional argument. she's low maintenance, we love that for her.


πŸ¦‹ DESCRIPTION πŸ¦‹

so here's the tea: who@ connects to TCP port 11 (that's the Systat port, iykyk) on host, and then just... prints whatever data it receives back. no filters, no curation, just vibes ✨

but wait, she does do a lil cleanup pass 🧚 before showing you the goods:

  • she strips out CR (\015) β€” bye bye carriage return, nobody asked
  • she converts unprintable characters into a visible format so your terminal doesn't get jump-scared πŸ’€

If host is not supplied, who@ connects to the local host instead. so if you're feeling lazy, just run it with no args and she'll check in on your own machine. self care, honestly 🌈

Some computers respond to port 11 with a list of active users. For example, they may be running:

tcpserver -RHl0 0 11 who

using tcpserver. that's the whole setup. server says who's online, who@ goes and asks. match made in heaven fr fr πŸ’…

and if you wanna go straight to the source (main character energy, honestly):

okay that's the whole page!! you now know who@ better than she knows herself. stay curious, stay slaying, and remember: port 11 is not a personality trait but it is a whole vibe πŸ’œ

this lil cutie lives in the General Commands Manual as who@(1) β€” mwah, go forth and query πŸŽ€
