fold

wrap each input line to fit in specified width

- Wrap each line to default width (80 characters):
fold [file]

- Wrap each line to width "30":
fold -w30 [file]

- Wrap each line to width "5" and break the line at spaces (puts each space separated word in a new line, words with length > 5 are wrapped):
fold -w5 -s [file]

fold [,OPTION/]... [,FILE/]...

Wrap input lines in each FILE, writing to standard output.

With no FILE, or when FILE is -, read standard input.

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
