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.
