If you're open to another command, "du -bc *" will produce a grand total. The "C" generates the total, and the "b" converts it from blocks to actual number of bytes similar to what the "ls -l" command produces.

Yes that's true.  Actually it was ls -la > somefile.  Once into somefile i eliminated some of the rows and I wanted to get the sum of that.  
Another alternative would be if i could do something like the du but only include those with the latest date(today)???

There are many ways to go about this, including using the "du" command as hfraser mentioned.

If you want to continue putting your file listing into a file to process, you could do something like this:
$ ls -l /some/dir | grep 'Sep 19' >somefile
$ total=0
$ for size in `cat somefile | awk '{print $5}'`
> do
> total=`expr $total + $size`
> done
$ echo $total

A simple awk script will tdo it for you.

{
  sum = sum + $5}
END {
 print sum
}

Just use cat filename | awk script.awk

Much easer and quicker to do
ls -la | awk '{t+=$5} END {print t}'

Thanks

IMHO, Tintin's solution is the most elegant - just add a grep for the date (depending on the date format of your system):

ls -la | grep 'Sep 19'  | awk '{t+=$5} END {print t}'

Yes.  Tintin always comes up with the most sexy solutions :-)  A bit late this time though :-(

With one less process :-)
ls -la | awk '/Sep 19/ {t+=$5} END {print t}'
