ethtool: Blink one or more LEDs on an interface for 10 seconds.
$ ethtool --identify ${eth0} ${10}
try on your machine
The command ethtool
is a Linux utility used to query and control network interfaces' settings and statistics. In this case, the command ethtool --identify ${eth0} ${10}
is being used with two arguments:
${eth0}
: This is a variable representing the network interface device name. The value of${eth0}
could be something likeeth0
, which refers to the first Ethernet interface on the system.${10}
: This is another variable that is likely representing the duration in seconds for the identification process. The value of${10}
is 10 seconds in this case.
So, the command is asking ethtool
to activate the identification mechanism on the network interface specified by ${eth0}
for a duration of ${10}
seconds. This mechanism often blinks the LEDs on the network interface, helping users identify the physical device among multiple network interfaces.

never run a command you are not sure if it is safe.
