I thought you were saying that the cause of "cat -n" /etc/fstab being
seen as one command was due to cat not having a full path, so I put a
full path in front of it. If you weren't saying lack of a full path is
the cause of "cat -n" being considered a single command, then my
prepending the full path produces no surprise at all.
