DESCRIPTION
Print information about GPIO lines.
Lines are specified by name, or optionally by offset if the chip option is provided.
If no lines are specified then all lines are displayed.
OPTIONS
- --by-name
- treat lines as names even if they would parse as an offset
- -c, --chip <chip>
- restrict scope to a particular chip
- -h, --help
- display this help and exit
- -s, --strict
- check all lines - don't assume line names are unique
- --unquoted
- don't quote line or consumer 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.
