John Peter (INDIA)
I have enabled hotplug in my kernel and is working. Now I need to extract the USB name .I have gone through the blkid documentation and I tried all the options with blkid. But I didnt get through. Below are some options I tried with blkid.
root:/> cat /proc/partitions
major minor #blocks name
31 0 256 mtdblock0
31 1 384 mtdblock1
31 2 7552 mtdblock2
31 3 7680 mtdblock3
31 4 512 mtdblock4
8 0 1974272 sda
root:/> blkid /dev/sda
root:/> blkid -h -t NAME=sda
Bus 001 Device 003: ID 1307:0165 Transcend Information, Inc. 2GB/4GB Flash Drive
Bus 001 Device 002: ID 148f:2770 Ralink Technology, Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
root:/> blkid |grep /dev/sda
root:/> blkid -p -o value -s TYPE /dev/sda
For all these commands, I didnt get any output. Actually I have renamed my USB as DEMO and I want to extract this name by using blkid. So please throw some light on this.

set the env var BLKID_DEBUG to 0xffff to see debugging output
otherwise, we dont have anything to do with blkid. if you dont understand it or its documentation, you really should be asking the people who write it, not us.
