NAME top
wdctl - show hardware watchdog status
SYNOPSIS top
wdctl [options] [device...]
DESCRIPTION top
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 top
-f, --flags list 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. -s, -settimeout seconds Set the watchdog timeout in seconds. -T, --notimeouts Do not print watchdog timeouts. -x, --flags-only Same as -I -T. -V, --version Display version information and exit. -h, --help Display help text and exit.
