Please be aware this is a Free Forum, people here help because they want to. Using bold large red caps and demanding service, is going to get you ignored real quick! Even if you was paying people, that's not going to get you very far.

My systems don't have a 'df -h' option, so I tested this wtih 'bdf -l" for HP-UX and "df -lk" for Solaris, so you'll need to substitute your 'df -h'.

I'm printing "disk", "percentage" and the "full or has space message"

Code:

## Disk full
bdf -l | awk '$5~/100|9[0-9]/{print $1,$5,"Disk Full" }'

## Disk has space
bdf -l |  awk '$5~/[0-8][0-9]/{ if ($5 != "100%") print $1,$5,"Disk has space" }'

so you should be able to use the following:

Code:

## Disk full
df -h | awk '$5~/100|9[0-9]/{print $0,$5,"Disk Full" }'

## Disk has space
df -h |  awk '$5~/[0-8][0-9]/{ if ($5 != "100%") print $1,$5,"Disk has space" }'

Thanks for reply

Both are not working for me I am using Ubuntu Servers. I had mounted some network partition on that System thats why it shows wrong output

Please help me 2 solve this problem
Thanks & regards

df -k |tail -n +2| awk '{if($4~/100|9[0-9]%/)print $NF" is out or running out of space ****"; else print $NF" has enough space"}'

if this doesn't work for you can you send a df -k output from your system
