45 utility displays the number of lines, words, and bytes contained in each

49 A line is defined as a string of characters delimited by a

54 character will not be included
57 A word is defined as a string of characters delimited by white space
59 White space characters are the set of characters for which the
61 function returns true.
62 If more than one input file is specified, a line of cumulative counts
63 for all the files is displayed on a separate line after the output for
