Apply ruler to clipboard?

Is there a method to apply a ruler to the text on the clipboard?

In the sense of wrapping at a particular length ?

pbpaste | fold -w 80 -s | pbcopy

UPDATE

Also, if the pbpaste | <process> | pbcopy pattern is in the area of what you want, it might also be worth looking at the bash fmt command as an element of the process.

Great. Thanks Rob – I’ll incorporate these suggestions.
