Wrap input lines to fit in specified width, writes each FILE (`-‘ means standard input), or standard input if none are given, to standard output, breaking long lines.

      fold [options]... [FILE]...

By default, `fold’ breaks lines wider than 80 columns. The output is split into as many lines as necessary.

`fold’ counts screen columns by default; thus, a Tab can count more than one column, Backspace decreases the column count, and CarriageReturn sets the column to zero.


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

 Break at word boundaries: the line is broken after the last blank
 before the maximum line length.  If the line contains no such
 blanks, the line is broken at the maximum line length as usual.

 Use a maximum line length of WIDTH columns instead of 80.
