NAME
fold —
fold long lines for finite width output
device
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.
-wwidth- Specifies width to use as a line width, instead of the default 80 characters.

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.
