SYNOPSIS
fold |
[-bs]
[-w width]
[file ...] |
DESCRIPTION
fold 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 characters.
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). If a blank
character does not exist within the width, then a longer line will still
be split at the width.
-
-
- -w
width
- Specifies width to use as a line
width, instead of the default 80 characters.
ENVIRONMENT
-

LC_CTYPE

EXIT STATUS

fold utility exits 0 on success, and >0 if an
error occurs.

BUGS
If underlining is present it may be messed up by folding.
Width should be a multiple of 8 if tabs are present, or
the tabs should be expanded using
expand(1) before using
fold.
