escape characters in sed

[Hans du Plooy <koffiejunkielistlurker@koffiejunkie.za.net>]

Hi guys,

I'm trying to do a search/replace on some text.  Looks like this:

1.2.3.4(1.2.3.4)

To my mind, this should replace the '(' with a space

sed 's/\\)/ /

But it does nothing.  Why?  How do I do this?

Thanks
Hans
