FOLD(1) BSD General Commands Manual FOLD(1)

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. Width 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).

SEE ALSO

expand(1), fmt(1)

STANDARDS

The fold utility conforms to IEEE Std 1003.1-2001 (‘‘POSIX.1’’).

BUGS

If underlining is present it may be messed up by folding.
