gpionotify [OPTIONS] <line>...
Wait for changes to info on GPIO lines and print them to standard
output.
Lines are specified by name, or optionally by offset if the chip
option is provided.
- --banner
- display a banner on successful startup
- --by-name
- treat lines as names even if they would parse as an offset
- -c, --chip
<chip>
- restrict scope to a particular chip
- -e, --event
<event>
- specify the events to monitor Possible values: 'requested', 'released',
'reconfigured'. (default is all events)
- -h, --help
- display this help and exit
- -F, --format
<fmt>
- specify a custom output format
- --idle-timeout
<period>
- exit gracefully if no events occur for the period specified
- --localtime
- convert event timestamps to local time
- -n, --num-events
<num>
- exit after processing num events
- -q, --quiet
- don't generate any output
- -s, --strict
- abort if requested line names are not unique
- --unquoted
- don't quote line or consumer names
- --utc
- convert event timestamps to UTC
- -v, --version
- output version information and exit
- 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 are taken as milliseconds unless units are specified. e.g. 10us.
Supported units are 's', 'ms', and 'us'.
- %o
- GPIO line offset
- %l
- GPIO line name
- %c
- GPIO chip name
- %e
- numeric info event type ('1' - requested, '2' - released or '3' -
reconfigured)
- %E
- info event type ('requested', 'released' or 'reconfigured')
- %a
- line attributes
- %C
- consumer
- %S
- event timestamp as seconds
- %U
- event timestamp as UTC
- %L
- event timestamp as local time
