Shell Programming and Scripting

HI
i included as u said. But while reading itself, it is suppressing blank spaces more than one occurance to one. so i am getting wrong data. Please review my code

Code:

c_line="/apps/source.txt"
targetfile="result.txt"
var1=0
while read c_line
do
var1=`grep -c "IIT   Chennai" $c_line`
echo $var1 >> $targetfile
if [ $var1 -ge 1 ]
then
val=`cut -c6-37 $$c_line`
echo $var >> $targetfile
fi
done<${c_line}

Have you getting any error?

can you post the content of "/apps/source.txt" ?

As u said, i included, but in vain. Please correct me if i am doing wrong.

Code:

while read c_line
do
echo $c_line >> $targetfile
var1=`grep -c "IIT   Chennai" $c_line`
if [ $var1 -ge 1 ]
then
val=`echo $$c_line | cut -c6-37 `
echo $var >> $targetfile
fi
done<${c_line}]

Ok, plz tell me what is the I/P contents and what is the expected O/P. We will provide you the solution depending on that.

My input file has the following data

<Record><sno>1</sno><empid>E0001</empid><name>Rejsh suderam</name><college>IIT Chennai </college>

Code:

while read c_line

You are modifying c_line variable. and now this contains the each line of the input file.
and grep expects a filename

use another variable name in while.
And use like this:

Code:

echo $line_var | grep ....
