     wwcc - word, line, and byte count

     wwcc [--ccllww] [_f_i_l_e _._._.]

DDEESSCCRRIIPPTTIIOONN
     The wwcc utility displays the number of lines, words, and bytes contained
     in each input _f_i_l_e (or standard input, by default) to the standard out-
     put.  A line is defined as a string of chacters delimited by a <newline>
     character, and a word is defined as a string of characters delimited by
     white space characters.  White space characters are the set of characters
     for which the isspace(3) function returns true.  If more than one input
     file is specified, a line of cumulative counts for all the files is dis-
     played on a separate line after the output for the last file.

     The following options are available:

     --cc      The number of bytes in each input file is written to the standard
             output.

     --ll      The number of lines in each input file is written to the standard
             output.

     --ww      The number of words in each input file is written to the standard
             output.

     When an option is specified, wwcc only reports the information requested by
     that option.  The default action is equivalent to specifying all of the
     flags.

     If no files are specified, the standard input is used and no file name is
     displayed.

     The wwcc utility exits 0 on success, and >0 if an error occurs.

     isspace(3)

     Historically, the wwcc utility was documented to define a word as a ``maxi-
     mal string of characters delimited by <space>, <tab> or <newline> charac-
     ters''.  The implementation, however, didn't handle non-printing charac-
     ters correctly so that ``  ^D^E  '' counted as 6 spaces, while
     ``foo^D^Ebar'' counted as 8 characters.  4BSD systems after 4.3BSD modi-
     fied the implementation to be consistent with the documentation.  This
     implementation defines a ``word'' in terms of the isspace(3) function, as
     required by IEEE Std1003.2 (``POSIX'').

     The wwcc function conforms to IEEE Std1003.2 (``POSIX'').
