Just replace the single quotes with double quotes. Single quotes are
keeping the $vars from being evaluated.
sed "s/REPLACE/${VALUE}/g" /tmp/x > /tmp/x.new

Thanks to both of you for responding. The empty quotes works best for
what I wanted to do (which I should have been clearer on in the first
place). I wanted to make the first choice in a menu the "default", ie,
just hit , and the empty quotes allow me to do that:
echo -e " Your selection, pl

Now that I think about it, you asked for how to check
for a response of just cr-lf. Here's what I should
have sent you:
#!/bin/bash
echo "Please answer yes or no: "
read answer
if [ x"$answer" = x"" ];
then
echo
echo "*** Invalid Response! ***"
echo
exit -1
fi
I think what I would do is put a check in for an empty
response before the case statement is ever reached.
Here's an example of what I mean:
#!/bin/bash
echo "Please answer yes or no: "
read answer
if [[ x"$answer" != x"yes" && x"$answer" != x"no" ]];
then
echo
echo "*** Invalid

Saul,
Thank you, that works beautifully. I modified it slightly to allow a
user to enter a search pattern on the command line, to wit:
#!/bin/sh
echo -e "Enter a file or pattern to search for...\n"
read file
for i in `find . -name "$file"`
do rm -i $i
done
exit 0
Thanks again!
