Loops are funny things, or they can do funny things from time to time.
You did not include the most important parts of the script, however, i
would use somthng like;
echo -n " Read more lines,? [Y/n]: "; read answer
if [ "$answer" = "Y" -o "$answer" = "y" -o "$answer" = "" ]; then
# do your stuff here
else
echo "Exiting..."
exit 1
fi
The above allows for upper and lower case, the -o "" allows for a C/R and
assumes "Y".
Anyway as i see it it is beter just to use the program "more" or program
"less" in a script.
