Vim: interactively check what's happening before substitute?

Question

vim has very powerful command tools. I can substitute 'Set's for all 'Array's:

:%s/Array/Set/g

But can I do this interactively as Unix commands(e.g. rm)? I hope vim to ask me whether I really want to replace a word, rather than substitute them all at once.

Answer 1

Yes, you can do this by appending another command as:

:%s/Array/Set/gc
