fold -- fold long lines for finite width output device
fold [-bs] [-w width] [file ...]
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.
The fold utility exits 0 on success, and >0 if an error occurs.
The fold utility conforms to IEEE Std 1003.1-2008 (``POSIX.1'').
The fold utility appeared in 1BSD.
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.
