NAME
fold —
fold long lines for finite width output device
SYNOPSIS
fold |
[ -bs][ -w width][ file ...] |
DESCRIPTION
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.
ENVIRONMENT
The
LANG,
LC_ALL and
LC_CTYPE environment variables affect the execution of
fold as described in
environ(7).
STANDARDS
The
fold utility conforms to IEEE Std 1003.1-2001 (“POSIX.1”).
BUGS
If underlining (see
ul(1)) is present it may be messed up by folding.
