[cs631apue] sum of file size

[jphillip]

Hi Professor, I was wondering if you could clarify the behavior for ls 
-l when printing the total size of the files.  The man page says "A 
total sum for all the file sizes is output on a line before the long 
listing." for both the -l (ell) and -s options.  Should this be in bytes 
and is this line modified by the -h and -k flags?  Also, should this 
total include the size of any files other than regular files?  Thanks!
