I would like to replace foo with bar and Foo with Bar. I can do

:s/Foo/Bar/g
:s/foo/bar/g

Can I do this in one command?

    I don't think it's possible but you can have a look at this plugin: https://github.com/tpope/vim-abolish it achieve exactly that, and more. – nobe4 May 19 '16 at 14:40

You could try this:

:s/\cfoo/\=submatch(0)[0] ==# 'F' ? 'Bar' : 'bar'/g

The replacement part of the substitution command is an expression which tests whether the first character of the pattern is F. If it is, the expression returns Bar, otherwise bar.
