Bourne-style for loops use <space> as the delimiter by default. To
change this behavior, modify the IFS variable (which is mentioned
but not explained in the sh manpage):
    
    $ OLDIFS=$IFS	# probably want to remember this value
    $ IFS=:
    $ export $IFS
    $ for i in $PATH; do
	echo $i
    done
    /home/will/bin
    /usr/local/sbin
    /usr/local/bin
    /usr/sbin
    /usr/bin
    /sbin
    /bin
    /usr/X11R6/bin
    /opt/
    /usr/games/
    $ IFS=$OLDIFS	# set it back to normal
    $ export $IFS	
    $ for i in $PATH; do
	echo $i
    done
    /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin:/opt/:/usr/games/
