Filesystem kbytes used avail capacity Mounted on

I want to cut and compare the capacity field with >85% , if it is >85% then i need to get an e-mail. I tried using cut but it didn't work properly. Any Help

This should get you close:

Code:
if [ `df -k /netprov | tail -1 | awk '{print $5'} | tr -d '%'` -gt 85 ]
then
    mail code goes here...

New question. IN the mail code i need to attach the df command output with the subject. I tried

Mail -s "subject" xxx@xxx.com < 'df -k /netprov'

gives output of df -k to the screen, but no e-mail. I checked with 70%, I know it is at 73%.

if [ `df -k /netprov | tail -1 | awk '{print $5'} | tr -d '%'` -gt 85 ]
then
mail code goes here...

There are other ways to do it but, at a minimum, you can simply use a temporary file.
Code:
if [ `df -k /netprov | tail -1 | awk '{print $5'} | tr -d '%'` -gt 85 ]
then
    df -k /netprov > /tmp/df_output.txt
    mailx -s "subject" xxx@xxx.com < /tmp/df_output.txt
    rm /tmp/df_output.txt
fi

or pipe the output as follows:
Code:
if [ `df -k /netprov | tail -1 | awk '{print $5'} | tr -d '%'` -gt 85 ]
then
    df -k /netprov | mailx -s "subject" xxx@xxx.com
fi
