.TH WD_IDENTIFY 8 "Dec 2015"
.UC 4
.SH NAME
wd_identify \- get watchdog driver identity
.SH SYNOPSIS
.B wd_identify
.RB [ \-c " \fIfilename\fR|" \-\-config\-file " \fIfilename\fR]"
.RB [ \-v "|" \-\-verbose ]
.SH DESCRIPTION
This utility opens
.IR /dev/watchdog
and gets the identification string from the watchdog which then is printed. The
device is closed afterwards.
.PP
An exit code of zero indicates success in getting the driver identity, while a
non-zero exit code indicates an error (not configured in the config file, no
device driver loaded, or driver failed to respond to ioctl request).
.PP
The wd_identify tool can only be used without causing a reboot if your kernel
is not compiled with the
.I CONFIG_WATCHDOG_NOWAYOUT
option enabled.
.PP
Note that the
.B watchdog
and/or
.B wd_keepalive
daemons may have to be stopped to make sure that
.B wd_identify
can access the watchdog device.
.SH OPTIONS
Available command line options are the following:
.TP
.BR \-c " \fIconfig-file\fR, " \-\-config\-file " \fIconfig-file"
Use
.I config-file
as the configuration file instead of the default
.IR /etc/watchdog.conf .
.TP
.BR \-v ", " \-\-verbose
Print more diagnostic messages. This covers parsing of the config file and also
causes the program to read-back the current watchdog time-out value (if
successful in opening the device).
.SH FILES
.TP
.I /dev/watchdog
The watchdog device.
.SH "SEE ALSO"
