Top Forums Shell Programming and Scripting Help with Comparing 2 strings from text Post 302541276 by aLHaNz on Saturday 23rd of July 2011 12:44:24 PM

I made a function something like this, I stored the extracted data in c1 but I can't compare both of the strings. Am I doing it wrong?

c1=`grep -w $title data.txt |grep -w $author|wc -l`
I wonder if this is correct..

Code:
function add_new_book
{
    echo "1) add_new_book"
	echo "Title: "
	read title
	echo "Author: "
	read author
	c1=`grep -w $title data.txt |grep -w $author|wc -l`
if [ $c1 -ne 0 ]
then
	echo "Price: "
	read price
	echo "Qty Available: "
	read qtyA
	echo "Qty Sold: "
	read qtyS
	echo "$title author price qtyA qtyS" >> data.txt
	echo "New book title "$title" added successfully!"
else
   echo " Name not Found"
fi
	
}
