vim: search replace over all writable buffers

Question

so

1GvG:s/..../g

can replace over an entire buffer

However, suppose I have multiple vim buffers loaded, and I want to do a :s over

Answer 1

Take a look at bufdo. There's also windo and tabdo. Keep in mind that per default Vim doesn't autowrite so for search/replace commands across buffer you need to turn on autowrite.
