NAME
     fold -- fold long lines for finite width output device

SYNOPSIS
     fold [-bs] [-w width] [file ...]

DESCRIPTION
     The  fold	utility  is  a	filter which folds the contents of the specified
     files, or the standard input if no files are specified, breaking the  lines
     to have a maximum of 80 columns.

     The options are as follows:

     -b      Count width in bytes rather than column positions.

     -s      Fold  line  after	the  last blank character within the first width
	     column positions (or bytes).

     -w width
	     Specify a line width to use instead of the default 80 columns.  The
	     width value should be a multiple of 8 if tabs are present,  or  the
	     tabs should be expanded using expand(1) before using fold.

ENVIRONMENT
     The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of
     fold as described in environ(7).

EXAMPLES
     Fold text in standard input with a width of 20 columns:

	   $ echo "I am smart enough to know that I am dumb" | fold -w 15
	   I am smart enou
	   gh to know that
	    I am dumb

     Same as above but breaking lines after the last blank character:

	   $ echo "I am smart enough to know that I am dumb" | fold -s -w 15
	   I am smart
	   enough to know
	   that I am dumb

SEE ALSO
     expand(1), fmt(1)

STANDARDS
     The fold utility conforms to IEEE Std 1003.1-2001 ("POSIX.1").

HISTORY
     The  fold utility first appeared in 1BSD.	It was rewritten for 4.3BSD-Reno
     to improve speed and modernize style.  The -b and -s options were added  to
     NetBSD 1.0 for IEEE Std 1003.2 ("POSIX.2") compliance.

AUTHORS
     Bill  Joy wrote the original version of fold on June 28, 1977.  Kevin Ruddy
     rewrote the command in 1990, and J. T. Conklin added the missing options in
     1993.

BUGS
     If underlining (see ul(1)) is present it may be messed up by folding.
