Re: How to replace "\" to "\\"

Thanks very much. The second works!

I am still wondering how it work. It seems to replace the " \%(\\\)\@<!\\\$(\\\)\@! " part to "\\\\". Would you help to explain the meaning of the replaced part?

  I have a text containing both "\" and '\\". Now I want to replace all the "\" to "\\", but leave those have already been "\\" alone. How can I achieve this?

 

 

:%s/\\/\\\\/g

:%s/\%(\\\)\@<!\\\%(\\\)\@!/\\\\/g
