Code:
sed "'s/'$stringOld'/'$stringNew'/g'" $file.bak > $file

using double quotes in sed,

you could just use it as
Code:
sed "s/$stringOld/$stringNew/g" $file.bak > $file

I know that but in his first post he has specified that the double quotes he has already tried and they are not working.

thanks
I finally figured it out. For anyone who is interested. The correct way to incorporate a script that replaces a user inputted string with spaces is as follows:

#!/bin/tcsh
set stringOld="$1"
shift
set stringNew="$1"
shift
#
#Replaces stringOld with stringNew inside fileName
foreach file ($*)
mv $file $file.bak
sed "s/$stringOld/$stringNew/g" $file.bak > $file
if ( { cmp $file $file.bak } )then
echo \*\*$file has not changed
rm $file.bak
endif

end

Notice that the $1's have to be encapsulated in double quotes as well as the sed arguments and options. Thanks for the help anyway guys.
