Applying an option to all opened files in Vim

Question

I do a vimdiff on 2 files. Now if I want to wrap 2 files then I need to apply :set wrap 2 times to each file separately.

Is there any way I can apply set wrap to both of them simultaneously without running same command twice?

Answer 1

windo does exactly what you want:

:windo set wrap

If you have multiple tabs, there is an equivalent tabdo to handle that case.

:tabdo set wrap
