a bashism:
Code:
echo $FNAME, $FILE_PATTERN 
s1.txt s2.lst s3.cvs s4.lst, *.lst

FILE=( $(echo $FNAME | grep -o "[^ ]"$FILE_PATTERN ))

echo ${FILE[0]}
s2.lst
echo ${FILE[1]}
s4.lst

It's not rock solid, as it does not insist on the dot preceding the extension (dot in FILE_PATTERN is used as a wildcard in grep regex).

Thanks @alister for the lesson of the day. I did realize after posting that it looks way too complicated for the need.
