search and replace for forward slash

Question

I am trying to replace multiple forward slashes "//" with a single slash "/".

How would you do that?

Also, How would you replace "asd/qwe/zxc" with "fgh/vbn"?

I was able to do this half way using below. But how do I use forward slash in the search string or the replace string.

:%s/asd.qwe.zxc/fgh/g

Answer 1

Either escape it or use different delimiters.

:s/\/\//\//g
:s#//#/#g

I prefer the latter.

Missed the second part:

:s/asd\/qwe\/zxc/fgh\/vbn/g
:s@asd/qwe/zxc@fgh/vbn@g

You can pick any delimiter that you want in the same manner that you could in ed or sed.

Answer 2

You can try using:

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

to replace all double slashes with single slashes (though I imagine a guru will show a much cooler way shortly :) ). The general idea is that you need to escape the slashes.
