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).
-
-w width
-
Specifies width to use as a line width, instead of the default 80 characters.
EXIT STATUS
The fold utility exits 0 on success, and >0 if an error occurs.
STANDARDS
The fold utility conforms to IEEE Std 1003.1-2008 (“POSIX.1”).
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.
