BDF

expertone — Fri, 02 Aug 2013 12:06:56 GMT

I am facing a minor issue , I dont know why ?? :)

when I am using BDF command i am getting the output, but when i am using " bdf | more "

it is not being executed, also bdf is showing perfect output but my cursor is not coming to

the " # " prompt. I always have to use "CTRL + C " to cancel it.

Can anybody will tell me what this issue is ????

Regards

Hi,
your bdf | more is in fact beeing executed. more is waiting to get some more input.

To immediately see the output, you could run:
bdf > /tmp/file &
tail -f /tmp/file

bye

That is what i am waiting for that for what " more " is waiting for.

i can see the output from your commands also.. but why mine is not being executed, but on other servers it is perfect.

You can get very, very strange results if you do a typo like this

# blabla > more

instead of

# blabla | more

so I would now check if "more" is still the original, e.g.

I have seen such before ...

# whence more

# file ...(insert the result here)

BTW, now you have 2 threads about the same question - confusing.

#
#
#
# whence more
/usr/bin/more
#
#
#
#
# file /usr/bin/more
/usr/bin/more: ELF-32 executable object file - IA64
#
#

this the output

Thanks regards

Looks good - I would try another command with more to see if this works or not. You may also try "man ...anything..." (e.g. man vgdisplay) to see if the sreen formatting works.

I think you problem is not 'more' but 'bdf'. You said:

>>also bdf is showing perfect output but my cursor is not coming to the " # "

So, if you run 'bdf' by itself you do not get the '#' prompt back, correct? That indicates that 'bdf' is still trying to access a file system but can't. Do you have any NFS mounts that it might be haning on? What if you run 'bdf -l' to just look at local file system? Does it come back normally then?

Yes you get what my problem is.

the error what ia am get while using " bdf | more is as below
#
# bdf | more
bdf: /usb: Permission denied

and the output of " bdf -l is perfect. there is no hang type of situation.

/usb ???

What did you mount?

Re: BDF

expertone — Fri, 02 Aug 2013 13:44:51 GMT

??.. we have not mounted any thing over there

Re: BDF

Patrick Wallek — Fri, 02 Aug 2013 14:31:02 GMT

You may need to check your /etc/mnttab file (it is a text file so you can cat it) and see what is listed there, and compare that to the 'bdf' output. The discrepancy will point you to the problem file system.

I would just run 'bdf' without using 'more'.

>and the output of " bdf -l is perfect. there is no hang type of situation.

Then you have a hung NFS mount.

Can you post the output from the command "mount" so we can see what filesystems you have mounted?
