     NAME
          fold - wrap each input line to fit in specified width

     SYNOPSIS
          fold [-bs] [-w width] [--bytes] [--spaces] [--width=width]
          [--help] [--version] [file...]

     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 fold.  fold
          prints the specified files, or the standard input when no
          files are given or the filename `-' is encountered, on the
          standard output.  It breaks long lines into multiple shorter
          lines by inserting a newline at column 80.  It counts screen
          columns, so tab characters usually take more than one
          column, backspace characters decrease the column count, and
          carriage return characters set the column count back to
          zero.

        OPTIONS
          -b, --bytes
               Count bytes rather than columns, so that tabs,
               backspaces, and carriage returns are each counted as
               taking up one column, just like other characters.

          -s, --spaces
               Break at word boundaries.  If the line contains any
               blanks, the line is broken after the last blank that
               falls within the maximum line length.  If there are no
               blanks, the line is broken at the maximum line length,
               as usual.

          -w, --width width
               Use a maximum line length of width columns instead of
               80.

          --help
               Print a usage message and exit with a status code
               indicating success.

          --version
               Print version information on standard output then exit.
