How can I include the period (.) in Vim's search and replace command? (replacing .html extensions)?

Question

When I do: /.html Vim looks for html

I would like to replace all the .html with .php

Something like this: :%s/html ext/php ext/g

Answer 1

Escape it. The . is a regex character which means "any character", so you need to escape it with \.

:%s/\.html/.php/g

Answer 2

Just escape the . character.

Search for /\.html

Answer 3

Use backslach to escape the dot.

/\.html will look for ".html".

Answer 4

Try escaping period character: /\.html
