HI kevin,

i'm getting below error while i execute that in my solaris system.

Code:
bash-3.00$ df -k | awk ' { if ($2>0 && $3/$2>=0.5) print "NOT OK"; else print "OK" } '
awk: division by zero
 record number 1

Pls check and suggest me.

I guess the awk of your version does not support "short circuit". try this:
Code:
df -k | awk ' { if ($2>0) if ($3/$2>=0.5) print "NOT OK"; else print "OK" } '

It's really strange. do you have more than one awk version on your system, try each of them with the following code.
Code:
df -k | awk ' $2>0 { if ($3/$2>=0.5) print "NOT OK"; else print "OK" } '
