SHOWCONSOLE(8)

🎀 NAME 🎀

Isserial — bestie, this little icon's whole job is figuring out if the tty sitting under stdin is a serial line. That's it. That's the whole vibe. 💅

(also real talk, this page spells it Isserial, isserial and iserial in three different places and we are keeping all three because consistency is not the main character here, ok?)

✨ SYNOPSIS ✨

isserial [< /dev/console]

Like, that's the entire invocation. Chef's kiss. 🫶

🌸 DESCRIPTION 🌸

Okay so here's the tea 🍓 — iserial checks whether the underlying character device of your current stdin is a serial line. That's the whole plot.

The glow-up use case? You point it at /dev/console as the current character device, and it'll tell you whether the console is a serial line. Lowkey iconic. 👑

And the exit status — write this down — iserial bails out with status 0 if stdin is a serial line, and not 0 if it isn't. Fr fr, 0 means yes. Don't @ me, that's just how exit codes work. 💀

⚠️ friendly reminder bestie: 0 = serial line, anything else = nope. Get it backwards and your boot scripts will be giving chaos demon energy. 😭
