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.

I trying to write a script that will make it easier for a friend that I finally talked into trying Freebsd setup a desktop.
This part of the script is suppose to change the line in the ttys file to allow kdm to start on boot.
Here is the relavent code:
KDMLINE="/usr/local/bin/kdm -nodaemon" REPLACELINE="/usr/X11R6/bin/xdm -nodaemon"
sed -e "s/$REPLACELINE/$KDMLINE/g" /etc/test/ttys > /etc/test/new
Here is the error I'm getting:
sed: 1: "s//usr/X11R6/bin/xdm -n ...": bad flag in substitute command: 'X'
I can't seem to figure this out and the only things I've found in searching is that sed had a problem with replacing strings over 4096 bytes, but I don't think this is the cause and all those post were years old.
This is on FreeBSD 5.3.
