NAME
fold - filter for folding lines
SYNOPSIS
fold [-b | --bytes] [-s | --spaces] [-c | --characters]
[-w | --width width ] [-width] [--help] [file]...
DESCRIPTION
The fold utility is a filter that folds lines from its input files,
breaking the lines to have a maximum of width column positions (or
bytes, if the -b option is specified). Lines are broken by the inser‐
tion of a NEWLINE character such that each output line (referred to
later in this section as a segment) is the maximum width possible that
does not exceed the specified number of column positions (or bytes). A
line is not broken in the middle of a character. The behavior is unde‐
fined if width is less than the number of columns any single character
in the input would occupy.
The -b and -c options are mutually exclusive and only one may be speci‐
fied.
If the CARRIAGE-RETURN, BACKSPACE, or TAB characters are encountered in
the input, and the -b option is not specified, they are treated spe‐
cially:
BACKSPACE The current count of line width is decremented by
one, although the count never becomes negative. fold
does not insert a NEWLINE character immediately
before or after any BACKSPACE character.
CARRIAGE-RETURN The current count of line width is set to 0. fold
does not insert a NEWLINE character immediately
before or after any CARRIAGE-RETURN character.
TAB Each TAB character encountered advances the column
position pointer to the next tab stop. Tab stops are
at each column position n such that n modulo 8
equals 1.
OPTIONS
The following options are supported:
-b, --bytes
Counts width in bytes rather than column positions. May not be
specified with -c option.
-s, --space
If a segment of a line contains a blank character within the first
width column positions (or bytes), breaks the line after the last
such blank character meeting the width constraints. If there is no
blank character meeting the requirements, the -s option has no
effect for that output segment of the input line.
-c, --characters
Counts width in characters rather than column positions. May not be
specified with -b option.
-w width | --width width | -width
Specifies the maximum line length, in column positions (or bytes if
-b is specified, or characters for -c). If width is not a positive
decimal number, an error is returned. The default value is 80.
--help
Print usage statement and exit.
OPERANDS
The following operand is supported:
file A path name of a text file to be folded. If no file operands
are specified, the standard input is used.
ENVIRONMENT VARIABLES
See environ(7) for descriptions of the following environment variables
that affect the execution of fold: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES,
and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 All input files were processed successfully.
>0 An error occurred.

NOTES
fold and cut(1) can be used to create text files out of files with
arbitrary line lengths. fold should be used when the contents of long
lines need to be kept contiguous. cut should be used when the number of
lines (or records) needs to remain constant.
fold is frequently used to send text files to line printers that trun‐
cate, rather than fold, lines wider than the printer is able to print
(usually 80 or 132 column positions).
fold might not work correctly if underlining is present.
