Wc counts lines, words, characters and (optionally) pages in the named files, or in the standard input if no name appears. A word is a maximal string of characters delimited by spaces, tabs or newlines.
If an argument beginning with one of ``lwcp'' is present, the specified counts (lines, words, characters, or pages) are selected by the letters l, w, c, or p. The default is -lwc unless -v is specified.
The -s option specifies that pages are pagesize lines long instead of the defaut 66.
The -v option asks for a verbose output format, with column headers and including pages by default.
