👑 stty(1) — aka "bestie, your terminal has FEELINGS and here's how to talk to it"

User Commands energy, section 1 of the manual. Yes bestie, this is stty, and it's about to become your new obsession. 💅

✨ NAME ✨

stty — change and print terminal line settings

Like, it literally pokes at how your terminal behaves. Groundbreaking. Iconic. 🎀

🌸 SYNOPSIS 🌸

stty [-F DEVICE | --file=DEVICE] [SETTING]...
stty [-F DEVICE | --file=DEVICE] [-a|--all]
stty [-F DEVICE | --file=DEVICE] [-g|--save]

Three whole moods, okay? 🦋

💖 DESCRIPTION 💖

Print or change terminal characteristics. That's the whole gig. 💅

Mandatory arguments to long options are mandatory for short options too. (Read that twice, it matters.)

🎀 OPTIONS 🎀

  • -a, --all — print all current settings in human-readable form
  • -g, --save — print all current settings in a stty-readable form
  • -F, --file=DEVICE — open and use DEVICE instead of standard input
  • --help — display this help and exit
  • --version — output version information and exit
Optional - before SETTING indicates negation. An * marks non-POSIX settings. The underlying system defines which settings are available. So like, your mileage may vary based on your system's vibe check. 🙈

🌈 Special characters:

  • * discard CHAR — CHAR will toggle discarding of output
  • eof CHAR — CHAR will send an end of file (terminate the input)
  • eol CHAR — CHAR will end the line

Handle the tty line connected to standard input. Without arguments, prints baud rate, line discipline, and deviations from stty sane. In settings, CHAR is taken literally, or coded as in ^c, 0x37, 0177 or 127; special values ^- or undef used to disable special characters. 🫶
