Debian - command line. Replace () in filenames with _

[AndroidApps]

Hi,

I've got a set of directories like this:
files\
files\a
files\b
etc...
files\z
files\0

In these directories there might be files with the following characters: ()
I need those characters replaced by underscores: _

Someone gave me the following command:

find ./ -type f -exec sed -i 's/\(\)/_/' {} \;

But this only seems to do a search and not actually replace the filenames.
Would anyone be able to give me the proper command?
I suck at regex.. B-)

Try this:

find ./ -type f -exec sed -i 's/\(\)/_/g' {} \;

Try this:

Thanks.
Unfortunately this did not rename any files.

$ find ./ -type f -exec sed -i 's/\(\)/_/g' {} \; 
$ 
$ ls
$ file (1.2.9).zip

Any more ideas?
