Can we have a option to check mount size in GB's....!

By using bdf?

You re-opened another ten year old thread with this same question; don't post duplicates or reopen old threads...read the LQ Rules. And have you read the man page on bdf, to see what it does?

You don't say what version of HP/UX you're using, or what you've done/tried on your own, or what your goal actually is. The df command can output what you need (and it also has a man page). And since HP/UX is a commercial, PAY FOR distro, have you called HP Support, or looked in their knowledgebase?

No direct use of bdf. Other linux tools to gain the data exist.

might give you the best output format.
But the values are in kilobytes.

But df -kP not working in HP-UX operating system

Linux® and Unix® are similar, but not exactly the same.

Ok...so as said before, either read the man page on bdf, script something to parse things out, or contact HP support. Again, HP/UX is a commercial, PAY FOR distro. In their knowledgebase, they have answers to this very question. Have you looked at the man page for the df command? The du command??

You are going to have to show some efforts of your own; further, you still haven't said what version of HP/UX you're using, and telling us "not working" isn't a good problem description....can you not post the message you're getting??

"But df -kP not working in HP-UX operating system"

Doohhh! I thought the OP meant in linux.

HP should have entire documentation for it's OS on their site. Otherwise you will have to search web for other man pages on that command. https://nixdoc.net/man-pages/HP-UX/man1m/bdf.1m.html

Really? What error message do you get? What version of HP-UX is it?
Try
Options -k and -P are described in https://nixdoc.net/man-pages/HP-UX/man1/df.1m.html
And mentioned in https://community.unix.com/t/looking...related/383399
