40 .Nd word, line, and byte count
49 utility displays the number of lines, words, bytes and characters contained in each
52 (or standard input, by default) to the standard output.
53 A line is defined as a string of characters delimited by a \*[Lt]newline\*[Gt]
55 and a word is defined as a string of characters delimited by white space
57 White space characters are the set of characters for which the
59 function returns true.
60 If more than one input file is specified, a line of cumulative counts
61 for all the files is displayed on a separate line after the output for
64 The following options are available:
67 The number of bytes in each input file
68 is written to the standard output.
70 The number of lines in each input file
71 is written to the standard output.
73 The number of characters in each input file
74 is written to the standard output.
76 The number of words in each input file
77 is written to the standard output.
80 When an option is specified,
84 information requested by that option. The
85 default action is equivalent to all the
88 having been specified.
90 The following operands are available:
93 A pathname of an input file.
97 are specified, the standard input is used and
98 no file name is displayed.
100 By default, the standard output contains a line for each
101 input file of the form:
102 .Bd -literal -offset indent
103 lines words bytes file_name
108 utility exits 0 on success, and \*[Gt]0 if an error occurs.
114 utility was documented to define a word as a ``maximal string of
115 characters delimited by \*[Lt]space\*[Gt], \*[Lt]tab\*[Gt] or \*[Lt]newline\*[Gt] characters''.
116 The implementation, however, didn't handle non-printing characters
117 correctly so that `` ^D^E '' counted as 6 spaces, while ``foo^D^Ebar''
118 counted as 8 characters.
122 modified the implementation to be consistent
123 with the documentation.
124 This implementation defines a ``word'' in terms of the
126 function, as required by
