i would suggest to use a "cut" you can use a loop to move the cut N times across the columns check for a value, then loop through the rows in a loop. The use of a nested loops. I have an example of using the cut and nested loops
Code:
for scene in `ls $dirname` 
do  
    if [ ! -d "${scene}" ]; then
        #this means its ...
        block.....Loop #function for single loop
        break  #exits the loops to give the counts
    fi
    currPath="${dirname}/${scene}"
    curFrame=`ls $currPath | wc -l`

    for line in `ls $currPath | cut -d "." -f 2- |sort | uniq`
    do
        count=`find $currPath -name "*.${line}"| wc -l `
        name1=$line #gives my my name per frame
        counttypes  #function "case statement"
    done #end for
    framecount=`expr ${framecount} + ${curFrame} `
done #end for

its may not be expert scripting but I am still learning it. Sorry had to edit some of the names and comments for posting...

iswblank

ISWBLANK(3)						     Linux Programmer's Manual						       ISWBLANK(3)

NAME

       iswblank - test for whitespace wide character

SYNOPSIS

       #include <wctype.h>

       int iswblank(wint_t wc);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       iswblank():
	      _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
	      or cc -std=c99

DESCRIPTION

       The  iswblank() function is the wide-character equivalent of the isblank(3) function.  It tests whether wc is a wide character belonging to
       the wide-character class "blank".

       The wide-character class "blank" is a subclass of the wide-character class "space".

       Being a subclass of the wide-character class "space", the wide-character class "blank" is disjoint from the  wide-character  class  "graph"
       and therefore also disjoint from its subclasses "alnum", "alpha", "upper", "lower", "digit", "xdigit", "punct".

       The wide-character class "blank" always contains at least the space character and the control character '	'.

RETURN VALUE

       The  iswblank()	function  returns  nonzero  if wc is a wide character belonging to the wide-character class "blank".  Otherwise it returns
       zero.

CONFORMING TO

       POSIX.1-2001.

NOTES

       The behavior of iswblank() depends on the LC_CTYPE category of the current locale.

SEE ALSO

       isblank(3), iswctype(3)
