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.
