GPIOGET(1)                          gpioget                         GPIOGET(1)

NAME
       gpioget - libgpiod command-line utility

SYNOPSIS
       gpioget [OPTIONS] <line>...

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 <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 <chip>
              restrict scope to a particular chip

       -C, --consumer <name> 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 <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.
