     DESCRIPTION
          This documentation is no longer being maintained and may be
          inaccurate or incomplete.  The Texinfo documentation is now
          the authoritative source.

          This manual page documents the GNU version of head.  head
          prints the first part (10 lines by default) of each given
          file; it reads from standard input if no files are given or
          when a filename of `-' is encountered.  If more than one
          file is given, it prints a header consisting of the file's
          name enclosed in `==>' and `<==' before the output for each
          file.

        OPTIONS
          head accepts two option formats: the new one, in which
          numbers are arguments to the option letters, and the old
          one, in which the number precedes any option letters.

          -c N, --bytes N
               Print first N bytes.  N is a nonzero integer,
               optionally followed by one of the following characters
               to specify a different unit.

               b    512-byte blocks.

               k    1-kilobyte blocks.

               m    1-megabyte blocks.

          -n N, --lines N
               Print first N lines.

          -q, --quiet, --silent
               Never print filename headers.

          -v, --verbose
               Always print filename headers.

          --help
               Print a usage message and exit with a status code
               indicating success.
          --version
               Print version information on standard output then exit.
