Linux command for short file descriptor?
I am in verse to know the short file descriptor of an ISO file. I have been assigned with a task to match the short file descriptor of an ISO file(to be provided to the customer) to check if thats "Kudgo Support tools" or not.
What linux command should I use?

I'm not sure I understand. If you want to check if two files are identical, use the md5sum

md5sum is the command which is quite different. It checks the integrity of ISO you download and helps to identify if that is correctly downloaded or not from remote repository.
What I am talking about is "Short File Descriptor" and "One Liner Descriptor".
I have been handed with an ISO and my Manager wants me to confirm if that short file descriptor says "Kudgo Support tools" or not.

There are various checklist you draw before handing over the product to the customer.

1. md5sum
3.Short File Descriptor
4. One Liner File Descriptor

For the first two, I ran:

#md5sum <name>.iso
#sha1sum <name>.iso

But I am unaware of the last two.

Maybe you can retrieve the information using:

isoinfo -d -i <name_of_iso_image>

The Command looks good but unfortunately that dint help me finding the short file description information.

Can yu guys suggest me further?

ajeetsinghraina, I didn't see you edited your post before posting mine (I was thinking about Volume Descriptor). However, at this point I'm not sure about what you mean for "Short File Descriptor" and "One Liner Descriptor", since these terms are not used in the ISO 9660 standard specification.

The pattern "Kudgo Support tools" makes me think at the volume label, but this information is already retrieved by the isoinfo command above (as well as volname, file or even the dd command). If you have an example of what these "descriptors" would appear, it should help to clarify.

When I googled "Kudgo Support tools", it gave me lots od references to what looks ike.

You must ask your boss where he got the inspiration for "short file descriptor" or "one liner file descriptor" since googling for them gave no matches.
