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.
13       If more than one device is specified then the output  is  separated  by
14       one blank line.
15
16       If  the  device is already used or user has no permissions to read from
17       the device than 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 spe‐
21       cific.
