       Read values of GPIO lines.

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

-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.
