DESCRIPTION
Read values of GPIO lines.
Lines are specified by name, or optionally by offset if the chip option is provided.

-
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
-

- -l, --active-low
-
treat the line as active low
- -p, --hold-period <period>
-

- --unquoted
-

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.
