39 .Nd word, line, character, and byte count
47 utility displays the number of lines, words, and bytes contained in each
50 or standard input (if no file is specified) to the standard output.
51 A line is defined as a string of characters delimited by a
54 Characters beyond the final
56 character will not be included
59 A word is defined as a string of characters delimited by white space
61 White space characters are the set of characters for which the
63 function returns true.
64 If more than one input file is specified, a line of cumulative counts
65 for all the files is displayed on a separate line after the output for
68 The following options are available:
69 .Bl -tag -width indent
71 The number of characters in the longest input line
72 is written to the standard output.
75 argument is specified, the longest input line of
77 files is reported as the value of the final
80 The number of bytes in each input file
81 is written to the standard output.
82 This will cancel out any prior usage of the
86 The number of lines in each input file
87 is written to the standard output.
89 The number of characters in each input file is written to the standard output.
90 If the current locale does not support multibyte characters, this
94 This will cancel out any prior usage of the
98 The number of words in each input file
99 is written to the standard output.
102 When an option is specified,
104 only reports the information requested by that option.
105 The order of output always takes the form of line, word,
107 The default action is equivalent to specifying the
113 If no files are specified, the standard input is used and no
114 file name is displayed.
115 The prompt will accept input until receiving EOF, or
117 in most environments.
123 environment variables affect the execution of
130 Count the number of characters, words and lines in each of the files
134 as well as the totals for both:
136 .Dl "wc -mlw report1 report2"
138 Find the longest line in a list of files:
140 .Dl "wc -L file1 file2 file3 | fgrep total"
144 utility was documented to define a word as a
147 characters delimited by <space>, <tab> or <newline> characters
149 The implementation, however, did not handle non-printing characters
151 .Dq Li "\ \ ^D^E\ \ "
152 counted as 6 spaces, while
154 counted as 8 characters.
158 modified the implementation to be consistent
159 with the documentation.
160 This implementation defines a
164 function, as required by
