Temp_var=`echo '"CUST_INFO","CUST_NAME","CUST_AGE"'`
head_file=`head -1 customer_file.txt`
Total_col_count=`awk -F"," '{print NF}' customer_file.txt|sort -u`

Code:
 
if [ $Total_col_count = 10 -a $Temp_var = $head_file ]
then 
echo "matched"
else "not matched"
fi

Thanks for the swift response but still facing the same. As I am guessing the row having double quotes that's way it is comparing. still unable to find the root cause.

error message
0403-012 A test command parameter is not valid.

Code:
 
Temp_var=`echo '"CUST_INFO","CUST_NAME","CUST_AGE"'`
head_file=`head -1 customer_file.txt`
Total_col_count=`awk -F"," '{print NF}' customer_file.txt|sort -u`
if [ $Total_col_count  -eq 10 -a $Temp_var  ==  $head_file ]
then 
echo "matched"
else "not matched"
fi

More chances that Total_col_count variable to hold more than one value in your case. So the if condition fails as your comparing it with single value 10. Print the value of Total_col_count and check before going for if condition to make sure it holds only single value and not multiple.

Hi,

I am getting single value for that column.

Used echo on each output value, i am getting only one valie at a time.
i am not understanding the nature of if condition if you have row comparision with in the double quotes. still i am getting the same error message.

Any help greatly appriciated.

Thanks

Ok.So your sure that the file customer_file.txt contains only one line.. Or many lines with same number of columns..? One little bug is that there is no echo statement in the else part.
Code:
if [ $Total_col_count  -eq 10 -a $Temp_var  ==  $head_file ]
then 
        echo "matched"
else 
        echo "not matched"
fi
