| 10 | .RI [ device ...] | |
| 013a4891 | 11 | .SH DESCRIPTION |
| 2002f9c4 SK |
12 | Show hardware watchdog status. The default device is |
| 13 | .IR /dev/watchdog . | |
| 14 | If more than one device is specified then the output is separated by | |
| 15 | one blank line. | |
| 16 | .PP | |
| b3dd29d1 KZ |
17 | If the device is already used or user has no permissions to read from the device than |
| 18 | .B wdctl | |
| 19 | reads data from sysfs. In this case information about supported features (flags) might be missing. | |
| 20 | .PP | |
| c372860d | 21 | Note that the number of supported watchdog features is hardware specific. |
