Rod, Take a look at what the shell replacement is actually doing. If you were to write the line manually it would look like this: sed -e 's/\/usr\X11R6\/bin\/xdm/\/usr\/local\/bin\/kdm/g' ... Right? But the shell doesn't escape the path separators (slashes). You need to escape them yourself in the variable assignments. Like this, KDMLINE='\/usr\/local\/bin\/kdm' &c And if there is only one occurrence per line, then you don't need the 'g' modifier. Hope that helps.
