Hello all, I am trying to read the 5th column of a log file which is the percentage filled space for a logical drive. I am writing a script which throws up a warning if this is greater than 60. But j is taken as a string and when I compare with 60 in the if statement, it does not work. How can I change string/ascii to int or float in shell so that the comparison works?

j=`echo $line | tr -s ' ' ' ' | cut -d' ' -f5`
if [ $j -gt 60 ]
then
echo "WARNING:$line"
fi

Can you give an example of the lines in the file?

I would say the problem is the way variable $j is created because this works on my solaris 9:

#!/bin/sh

j="59"
if [ $j -gt 60 ]
then
echo "greater than 60"
fi

while read line
do
set -f
set -- $line
j=$5
if [ $j -gt 60 ]
then
echo "Value of j is $j"
echo "WARNING:$line"
fi
done < dblist1

Found out ... This is working
