======= GPIOGET ======= :Date: June 2026 NAME ==== gpioget - libgpiod command-line utility SYNOPSIS ======== **gpioget** [*OPTIONS*] **... DESCRIPTION =========== Read values of GPIO lines. Lines are specified by name, or optionally by offset if the chip option is provided. OPTIONS ======= **-a**, **--as-is** leave the line direction unchanged, not forced to input **-b**, **--bias** specify the line bias Possible values: 'pull-down', 'pull-up', 'disabled'. (default is to leave bias unchanged) **--by-name** treat lines as names even if they would parse as an offset **-c**, **--chip** restrict scope to a particular chip **-C**, **--consumer** consumer name applied to requested lines (default is 'gpioget') **-h**, **--help** display this help and exit **-l**, **--active-low** treat the line as active low **-p**, **--hold-period** wait between requesting the lines and reading the values **--numeric** display line values as '0' (inactive) or '1' (active) **-s**, **--strict** abort if requested line names are not unique **--unquoted** don't quote line names **-v**, **--version** output version information and exit 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. 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.
