  | Surely there

try
	eval set -- $( mount -t tmpfs | while read -r line; do
                      fs=${line#tmpfs on }; fs=${fs% type tmpfs*};
                      echo "'${fs}'"; done )

after which "$@" should be the tmpfs moounted filesystems, even if
they contain odd characters (including spaces).

Then
	for fs
	do
		whatever you want using "${fs}"
	done

Do this in a function, so you get a free $@ to play with...
