Shell Programming and Scripting

The desirable output can be achieved by the given solution. Why do you want to use sed command specifically. Is there any particular reason behind it?

When I print $line it showing as x/y/z it not showing </tag>. We have two files ,need to append this details from one file to another.

Show whatever output you got.

It is not appending any thing to the file.
Here is my code:

touch optFile

a1="X"

echo $a1


cat $A2 | while read line
do
if [ "$line" = ".*\<tag name\=\"$a1\".*" ] ; then

echo "$line" >> optFile
echo "\<sometext\/\>" >> optFile
else
echo "$line" >> optFile
fi
done

And O/P file as below: It was same as I/P file
<tag name="X">


</tag>
<tag name="Y">

</tag>
