Find and replace strings in vim on multiple lines

Question

I can do :%s///g for replacing a string across a file, or :s///

Answer 1

We don't need to bother entering the current line number.

If you would like to change each foo to bar for current line (.) and the two next lines (+2), simply do:

:.,+2s/foo/bar/g

If you want to confirm before changes are made, replace g with gc:

:.,+2s/foo/bar/gc
