<a name=


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 [OPTION]... [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 may count more
	than one column, backspace decreases the column count, and carriage
	return 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.

`-w WIDTH'
	Use a maximum line length of WIDTH columns instead of 80.

"The general attitude seems to be that people should wear square shoes, because squares are easier to design and manufacture than foot shaped shoes. If the shoe industry has gone the way of the computer industry it would now be running a $200-a-day course on how to walk, run and jump in square shoes." - Alan Kay
