NAME

6       wdctl - show hardware watchdog status
7

SYNOPSIS

9       wdctl [options] [device...]
10

DESCRIPTION

12       Show hardware watchdog status. The default device is /dev/watchdog. If
13       more than one device is specified then the output is separated by one
14       blank line.
15
16       If the device is already used or user has no permissions to read from
17       the device, then wdctl reads data from sysfs. In this case information
18       about supported features (flags) might be missing.
19
20       Note that the number of supported watchdog features is hardware
21       specific.
