That's not a good idea, because it will break if the pathname
already contains spaces.
Another better possibility is to modify the shell's $IFS:
OLD_IFS="$IFS"
IFS=/
set x $VARIABLE
shift
IFS="$OLD_IFS"
Note the "x" and the shift. This prevents breakage of the
contents of $VARIABLE begins with a "-". And do not forget
to reset $IFS to the old value, otherwise you ight run into
very strange effects. ;-)
