FOLD(1) General Commands Manual FOLD(1) 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). If a blank character does not exist within the width, then a longer line will still be split at the width. -w width Specifies width to use as a line width, instead of the default 80 characters. ENVIRONMENT LC_CTYPE EXIT STATUS The fold utility exits 0 on success, and >0 if an error occurs. SEE ALSO expand(1), fmt(1) STANDARDS The fold utility conforms to IEEE Std 1003.1-2008 ("POSIX.1"). HISTORY The fold utility appeared in 1BSD. 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. NetBSD 8.0 May 12, 2012 NetBSD 8.0
