$ man -k wrap | fgrep line
Text::Wrap (3pm) - line wrapping to form simple paragraphs
fold (1) - wrap each input line to fit in specified width
ggz-wrapper (6) - GGZ Gaming Zone command line core client
Hmm, 'fold' looks promising...
$ fold --help
Usage: fold [OPTION]... [FILE]...
Wrap input lines in each FILE (standard input by default), writing to
standard output.
Mandatory arguments to long options are mandatory for short options too.
-b, --bytes count bytes rather than columns
-s, --spaces break at spaces
-w, --width=WIDTH use WIDTH columns instead of 80
--help display this help and exit
--version output version information and exit
