    <p>The sed works fine and is not a problem.  The only problem with
      the script is with: alias update_makefiles 'string'<br>
    </p>
    <p>It's just that the string part is too long for csh [

    </p>
    <p>Which is why if you shorten the string, for example split it into
      two alias (like update_makefiles01 and update_makefiles02), then
      the script works fine:<br>

    <p>Note: The for loop pseudo code in msg18738 I realize I have a
