Search and replace /'s in VI

Question

I was wondering how I would search and replace all /'s with -'s in vi.

%s///-/g doesn't work obviously.

Answer 1

Try escaping your /s, with a \.

\/. yes, it looks awful. That's how I remember it :P

Answer 2

You can use any delimiter you wish, not just /. For example, !:

%s!/!-!g

This way, / becomes non-special and doesn't have to be escaped.

Answer 3

replacing separator is not always /.

Try

%s;hoge/hoge;fuga/fuga;g

in the text of "http://hoge/hoge"
