wdctl - show hardware watchdog status
wdctl [options] [device...]
Show hardware watchdog status. The default device is /dev/watchdog.
If more than one device is specified then the output is separated by
one blank line.
If the device is already used or user has no permissions to read from
the device, then wdctl reads data from sysfs. In this case
information about supported features (flags) might be missing.
Note that the number of supported watchdog features is hardware
specific.

Print only the specified flags.
-F, --noflags
Do not print information about flags.
-I, --noident
Do not print watchdog identity information.
-n, --noheadings
Do not print a header line for flags table.
-o, --output list
Define the output columns to use in table of watchdog flags.
If no output arrangement is specified, then a default set is
used. Use --help to get list of all supported columns.
-O, --oneline
Print all wanted information on one line in key="value" output
format.
-r, --raw
Use the raw output format.

Set the watchdog timeout in seconds.
-T, --notimeouts
Do not print watchdog timeouts.
