I don't want to plagerize so I give credit to Dale Dougherty and Arnold Robins who wrote "sed and awk" which I mentioned in my previous post (you really should buy it). It may not be exactly what you want but should be really close:
#!/bin/sh
ls -sl $* | awk'
#filesum: list files and total size in bytes
#input: long listing produced by "ls -l"
#1 output column headers
BEGIN { print "BYTES", "\t", "FILE" }
#2 test for 9 fields; files begin with "-"
NF == 9 && /^-/ {
sum += $5 # accumulate size of file
++filenum # count number of files
print $5, "\t", $9 # print size and filename
}
#3 Test for 9 fields; directory begins with "d"
NF == 9 && /^d/ {
print "<dir>", "\t", $9 #print <dir> and name>
}
#4 test for ls -lR line .dir:
$1 ~ /^\..*:$/ {
print "\t" $0 #print that line proceeded by a tab
}
#5 once all is done,
END {
#print total file size and number of files
print "Total: ", sum, "bytes (" filenum " files)"
}'
This will count the total number of files and their total combined size. I highly recommend the sed and awk book. I actually carry it in my briefcase all the time because it is just such a good reference book and awk is such a powerfull tool. It is well worth the time to learn the ins and outs of awk.

IGAWK(1) Utility Commands IGAWK(1)
NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
