# [SYNOPSIS](#SYNOPSIS)

**gpioget** \[*OPTIONS*] *<line>*...

# [DESCRIPTION](#DESCRIPTION)

Read values of GPIO lines.

Lines are specified by name, or optionally by offset if the chip option is provided.

# [OPTIONS](#OPTIONS)

[**-a**, **--as-is**](#a)

leave the line direction unchanged, not forced to input

[**-b**, **--bias** <bias>](#b)

specify the line bias Possible values: 'pull-down', 'pull-up', 'disabled'. (default is to leave bias unchanged)

[**--by-name**](#by)

treat lines as names even if they would parse as an offset

[**-c**, **--chip** <chip>](#c)

restrict scope to a particular chip

**-C**, **--consumer** <name> consumer name applied to requested lines (default is 'gpioget')

[**-h**, **--help**](#h)

display this help and exit

[**-l**, **--active-low**](#l)

treat the line as active low

[**-p**, **--hold-period** <period>](#p)

wait between requesting the lines and reading the values

[**--numeric**](#numeric)

display line values as '0' (inactive) or '1' (active)

[**-s**, **--strict**](#s)

abort if requested line names are not unique

[**--unquoted**](#unquoted)

don't quote line names

[**-v**, **--version**](#v)

output version information and exit

## [Chips:](#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:)

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.
