The outvar=`cat test.out` is not great from a few things:-
The content of outvar will contain the entire file, so leading spaces, any headers (I see you've turned them off) and any end of line/end of file marker so the numerical comparison is a bit awkward. Your test in [[ & ]] uses the = operator, but this is a string comparison, and I'm not sure if this structure is supported in true ksh either. This is more of a bash syntax. ksh might also accept it, but I think it is only looking for file information instead. Your test (assuming that the file always just contains a numeric value) could probably be written as:

Code:

outvar=$(<test.out)
if [ $outvar -eq 0 ]
then
   echo "No Duplicate records Found: $outvar"  
else  
   echo "Num of Duplicate records Found: $outvar"  
fi

If it gives a bit of trouble, it is likely that the other characters read in from the file are the problem. You might try adding a line after the read such as typeset -i outvar=$outvar to see if that strips all the other things away and just assigns it the integer value. There are various typeset options for true ksh that have not transferred into bash or other pseudo-ksh so I'm hoping you have a true ksh. I can't test the syntax properly because I've not got a true ksh available so this bit is from memory of about 5 years ago.



Do either of these suggestions help?
