GPIOGET(1)

🦋 gpioget — the libgpiod command-line utility, bestie edition ✨

okay so this is gpioget, one of the libgpiod command-line utilities, and it's literally here to read the values of GPIO lines for you 💅

✨ SYNOPSIS ✨

gpioget [OPTIONS] <line>...

🌸 DESCRIPTION 🌸

It reads the values of GPIO lines. That's the whole vibe. 👑

You specify your lines by name, or optionally by offset — but only if you also pass the chip option. iykyk 🫶

💖 OPTIONS 💖

• -a, --as-is — leaves the line direction unchanged instead of forcing it to input. no cap, it just doesn't touch it 🎀
• -b, --bias <bias> — says what bias the line should have. Possible values: 'pull-down', 'pull-up', 'disabled'. the default is to leave the bias unchanged, so if you don't say anything, nothing happens 🌈
• --by-name — treats your lines as names even if they'd otherwise parse as an offset. protects your name from being read as a number 💀
• -c, --chip <chip> — restricts the scope to one particular chip 🔍
• -C, --consumer <name> — the consumer name applied to the requested lines. default is 'gpioget' ⭐
• -h, --help — displays this help and exits. the classic escape hatch 🙈
• -l, --active-low — treats the line as active low 🔥
• -p, --hold-period <period> — waits between requesting the lines and reading the values. patience is a virtue bestie 🧚
• --numeric — displays line values as '0' (inactive) or '1' (active). numbers only, no thoughts 🍓
• -s, --strict — aborts if the requested line names are not unique. it will NOT let duplicates slide 😭
• --unquoted — doesn't quote line names. free the names 💜
• -v, --version — outputs version information and exits 👑

🎀 Chips: 🎀

A GPIO chip may be identified by number, name, or path. e.g. '0', 'gpiochip0', and /dev/gpiochip0 all refer to the same chip. three looks, one icon 👑

🦋 Periods: 🦋

Periods are taken as milliseconds unless units are specified. e.g. 10us. Supported units are 'm', 's', 'ms', and 'us' for minutes, seconds, milliseconds and microseconds respectively. so m = minutes, s = seconds, ms = milliseconds, us = microseconds — don't mix them up bestie 💅
