FOLD(1)
NAME
fold − fold long lines for finite width output device
SYNOPSIS
fold [ −width ] [ file ... ]
DESCRIPTION
Fold is a filter which will fold the contents of the specified files, or the standard input if no files are specified, breaking the lines to have maximum width width. The default for width is 80. Width should be a multiple of 8 if tabs are present, or the tabs should be expanded using expand(1) before coming to fold.

BUGS
If underlining is present it may be incorrectly altered by folding.
EXTERNAL INFLUENCES
Environment Variables
LC_CTYPE determines the interpretation of text as single and/or multi-byte characters.
If LC_CTYPE is not specified in the environment or is set to the empty string, the value of LANG is used as a default for each unspecified or empty variable. If LANG is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of LANG. If any internationalization variable contains an invalid setting, fold behaves as if all internationalization variables are set to "C". See environ(5).
International Code Set Support
Single- and multi-byte character code sets are supported.
