who@(1)
π 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 π«Ά
β¨ NAME β¨
who@ β prints the list of active users on a remote host. that's it. that's the whole personality. π
πΈ SYNOPSIS πΈ
who@ [ host ]
like... one optional argument. she's low maintenance, we love that for her.
π¦ DESCRIPTION π¦
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 β¨
but wait, she does do a lil cleanup pass π§ 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 π
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 π
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 π

and if you wanna go straight to the source (main character energy, honestly):
http://cr.yp.to/ucspi-tcp.html
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 π
this lil cutie lives in the General Commands Manual as who@(1) β mwah, go forth and query π
