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 characters in the longest line of each input file
71 is written to the standard output.
73 The number of lines in each input file
74 is written to the standard output.
76 The number of characters in each input file
77 is written to the standard output.
79 The number of words in each input file
80 is written to the standard output.
83 When an option is specified,
87 information requested by that option.
88 The default action is equivalent to all the flags
90 having been specified.
92 The following operands are available:
95 A pathname of an input file.
99 are specified, the standard input is used and
100 no file name is displayed.
102 By default, the standard output contains a line for each
103 input file of the form:
104 .Bd -literal -offset indent
105 lines words bytes file_name
112 utility was documented to define a word as a ``maximal string of
113 characters delimited by
119 The implementation, however, didn't handle non-printing characters
120 correctly so that `` ^D^E '' counted as 6 spaces, while ``foo^D^Ebar''
121 counted as 8 characters.
125 modified the implementation to be consistent
126 with the documentation.
127 This implementation defines a ``word'' in terms of the
129 function, as required by
134 option is a non-standard extension, compatible with the
136 option of the GNU and
