Hi all

How can I check the UUID of the disk partition in which I am currently working.

Are you using multiple partitions? if not "cat /dev/disk/by-uuid" will show you.

Yes I am using multiple partitions. So I have more than more than uuids.
So now what to do.

Try this:

Quote:

ls -l /dev/disk/by-uuid

Use the command "blkid" as any user.

Let me be more descriptive. Suppose I am working in Desktop directory. Now I want to now that what is the uuid of the partition on which this Desktop directory is present.

blkid will print all the uuids which will force me to select the correct one that I need.

Not sure I understand your questions, but blkid doesn't make you "choose" anything, it just prints the UUIDs of every partition. I don't know why that is a big deal, but if you only want to print the UUID for a specific partition, you can use the command "blkid | grep sdaX" (or hda, or what type of partition you have". There is no tool that will tell you the partition a particular directory is on, and give you the UUID of that partition.

Is it that you don't know how you hard drive is partitioned? If this is the case you can use the "df" command, normally used to determine disk usage, to print a list of your partitions, and what parent directories are mounted on them. The only thing that this command won't print is swap partitions, but you can determine this by process of elimination.

Or run mount without arguments.

Here are some steps to do what you want from the command line; they could be implemented in a script

Code:

c@CW8:~$ df ~/Desktop
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/root             14593252   4633784   9959468  32% /
c@CW8:~$ ll /dev/root
lrwxrwxrwx 1 root root 4 Feb 27 08:01 /dev/root -> sda7
c@CW8:~$ ll /dev/disk/by-uuid/ | grep sda7
lrwxrwxrwx 1 root root 10 Feb 27 08:01 7750b4f2-3428-49b8-8654-698d4c40e656 -> ../../sda7

Hi Catkin

This worked the way I expected. Thanks for your help. Thanks to others also.
