## 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, 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.

## OPTIONS
### -f --flags
           Print only the specified flags.

### -F --noflags

### -I --noident

### -n --noheadings

### -o --output
           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.
