NAME
wdctl - show hardware watchdog status
SYNOPSIS
wdctl [options] [device...]
DESCRIPTION
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 than 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 spe-
cific.
