44 .Nd word, line, character, and byte count
52 utility displays the number of lines, words, and bytes contained in each
55 (or standard input, by default) to the standard output.
56 A line is defined as a string of characters delimited by a <newline>
58 and a word is defined as a string of characters delimited by white space
60 White space characters are the set of characters for which the
62 function returns true.
63 If more than one input file is specified, a line of cumulative counts
64 for all the files is displayed on a separate line after the output for
67 The following options are available:
70 The number of bytes in 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 is written to the standard output.
77 If the current locale does not support multibyte characters, this
82 The number of words in each input file
83 is written to the standard output.
86 When an option is specified,
88 only reports the information requested by that option.
89 The default action is equivalent to specifying the
96 If no files are specified, the standard input is used and no
97 file name is displayed.
104 environment variables affect the execution of
111 Count the number of characters, words and lines in each of the files
115 as well as the totals for both:
117 .Dl "wc -mlw report1 report2"
121 utility was documented to define a word as a ``maximal string of
122 characters delimited by <space>, <tab> or <newline> characters''.
123 The implementation, however, didn't handle non-printing characters
124 correctly so that `` ^D^E '' counted as 6 spaces, while ``foo^D^Ebar''
125 counted as 8 characters.
129 modified the implementation to be consistent
130 with the documentation.
131 This implementation defines a ``word'' in terms of the
133 function, as required by
