Subject: udev to obtain hard drive serial number
Date: Thu, 10 Nov 2011 15:06:58 +0000 [thread overview]
Message-ID: <44057.128.173.192.90.1320937618.squirrel@webmail.tuffmail.net> (raw)
What's the most stable way in which to obtain a hard drive serial number
using recent Linux kernels and udev. Normal users may call udevadm like
this to get the serial number:
/sbin/udevadm info --query=property --name /dev/sda | grep ID_SERIAL_SHORT
| tr = " " | awk '{print $2}'
output looks like this:
E3834563JPSNTN
How stable/reliable is this approach compared to other tools such as
hdparm, etc. Is there a better way to do this with udev?
Thanks for any advice,
Brad
