why don't you have your script check to see if it's interactive when running on the remote box and, if no, supply a default answer to your query?

or you can just remove the "< /dev/tty" ...

The requirement is such that it need to read response for each processing, hence cannot do away with reading from terminal.

In the script which is executed on remote code looks somewhat like this.

Code:
while read line
do

read response < /dev/tty
if [ $response = 'Y' ]; then
.....
fi

done < $datafile

on executing through script it says /dev/tty : cannot open.

Please advise.

Regards,
Rishi

try ...
Code:
while read line
do
    echo "Y/N? \c"
    read response
    if [ $response = 'Y' ]; then
    .....
    fi
done < $datafile

PHP
Code:
while read line
do
    echo "Y/N? \c"
    read response
    if [ $response = 'Y' ]; then
    .....
    fi
done < $datafile

This wont work, because my default input is connected to file, and if I give read in same loop it will read from file instead from terminal.

Therefore I had specifically given
Code:
read response < /dev/tty

    fi
done < $datafile
exec 4<&-
