NAME

       wc - word count

SYNOPSIS

       wc [ -lwrbc ] [ file ...  ]

DESCRIPTION

       Wc  counts lines, words, runes, syntactically-invalid UTF codes and bytes in the named files, or in the standard input if no file is named.
       A word is a maximal string of characters delimited by spaces, tabs or newlines.	The count of runes includes invalid codes.

       If the optional argument is present, just the specified counts (lines, words, runes, broken UTF codes or bytes) are selected by the letters
       l, w, r, b, or c.  Otherwise, lines, words and bytes (-lwc) are reported.

SOURCE

       /sys/src/cmd/wc.c

BUGS

       The Unicode Standard has many blank characters scattered through it, but wc looks for only ASCII space, tab and newline.
       Wc should have options to count suboptimal UTF codes and bytes that cannot occur in any UTF code.

NAME

       wc - count words, lines, and bytes or characters in a file

SYNOPSIS

       [file]...

DESCRIPTION

       The  command  counts lines, words, and bytes or characters in the named files, or in the standard input if no file names are specified.	It
       also keeps a total count for all named files.

       A word is a string of characters delimited by spaces, tabs, or newlines.

   Options
       recognizes the following options:

	      Report the number of bytes in each input file.

	      Report the number of newline characters in each input file.

	      Report the number of characters in each input file.

	      Report the number of words in each input file.

       The and options are mutually exclusive.	Otherwise, the and or options can be used in any combination to specify that a	subset	of  lines,
       words, and bytes or characters are to be reported.

       When any option is specified, reports only the information requested.  If no option is specified, the default output is

       When a file is specified on the command line, its name is printed along with the counts.

   Standard Output
       By default, the standard output contains an entry for each input file in the form:

	      newlines words bytes file

       If the option is specified, the number of characters replaces the bytes field in this format.

       If any option is specified, the fields for the unspecified options are omitted.

       If no file operand is specified, neither the file name nor the preceding blank character is written.

       If  more than one file operand is specified, an additional line is written at the end of the output, of the same format as the other lines,
       except that the word (in the POSIX locale) is written instead of a file name and the total of each column is written as appropriate.

       Under UNIX Standard environment, a word is a string of characters delimited by spaces, tabs, newline,  carriage-return,	vertical  tab,	or
       form-feed.

RETURN VALUE

       exits with one of the following values:

	      Successful completion.
	      An error occurred.

EXTERNAL INFLUENCES

       For information about the UNIX Standard environment, see standards(5).

   Environment Variables
       determines the range of graphics and space characters, and the interpretation of text as single- and/or multibyte characters.

       determines the language in which messages are displayed.

       If or is not specified in the environment or is null, they default to the value of

       If is not specified or is null, it defaults to (see lang(5)).

       If any internationalization variable contains an invalid setting, they all default to See environ(5).

   International Code Set Support
       Single- and multibyte character code sets are supported.  with a newline character, the count will be off by one.

WARNINGS

       The  command counts the number of newlines to determine the line count.	If a text file has a final line that is not terminated with a new-
       line character, the count will be off by one.

EXAMPLES

       Print the number of words and characters in

       The following is printed when the above command is executed:

       where words is the number of words and chars is the number of characters in
