Shell Programming and Scripting

Here's what the shell (korn) script is doing:
1. Prompt for input
2. Read a file using the cat and the while read command.
3. Get a field on the record and hold that value in a variable.
4. Within the process, I then need to prompt the user again to ask them if they are sure they want to make a change.
PROBLEM - When I do the second read to prompt user, the value in the read varaible is the record from the file.

CODE:
typeset -u DESC
typeset -u RESPONSE

echo "Enter new type description:\c"
read DESC

cat filename | while read rec
do
type=`echo "$rec" | cut -c1-2`
if [ "$type" = "01" ]
then
#== Change the description ==#
while true
do
echo "Are you sure you want to change the description (Y/N) :\c"
read RESPONSE
if [ $RESPONSE != "Y" ] && [ $RESPONSE != "N" ]
then
echo "\nInvalid response, enter a Y or N \c"
continue
else
break
fi

done

if [ "$RESPONSE" = "Y" ]
then
echo "$type,$DESC" >> new_file
else
echo "$rec" >> new_file
fi

else #== Not an 01==#
echo "$rec" >> new_file
fi

done

Try this:

read RESPONSE < /dev/tty

Thanks, that worked.

I know dev is a directory. What is tty?

/dev is a directory that by convention contains only special files. /dev/tty is a special file that refers to your terminal. So no matter which terminal you are using. /dev/tty is your terminal. You can read from it or write to it.
