Wow Nils, now if I could just understand what your code is actually 
doing. I did solve the problem with a function and word expansion. I 
pass each line to a function that receives the line as a parameter. If 
there are spaces in it, it gets treated like several command line 
parameters.

Here's my code. -

function ReplaceSpaces {
     # loop through command line parameters, concatenating them with %20
     # Assign the value of $1 to ThisLine
     ThisLine="$1"
     # shift command line parameters to the next one
     shift
     # if the command line arguments did not expire after the first 
shift, there must be spaces
     while [ "$1" != "" ]
          do
            # Concatenate ThisLine with %20, and the next command line 
argument
            ThisLine="$ThisLine%20$1"
            # shift to the next command line argument
            shift
     done
     return
}

And it gets called like so -

ReplaceSpaces $ThisLine

It works great, now all spaces in urls within my Google site map get 
replaced with %20, and the script runs just fine now.

Later, Ray Parrish
