Automator: shell script to change file permissions

Question

Hey guys,
Just created a workflow to copy some files from one location to another.
Second thing I want to do is run a shell-script to set some file permissions recursively, some for the folders, the other for the files.
I figured I could do the following:
cd /IntoAFolder
find . -type d -exec chmod 770 {} \;
Unfortunately, this seems to be needed to be done as a sudo'er and thus requires the user's password.
So the question is, how do I get that password and hand it to the shell script or is there another way of doing this?

Answer 1

What I want to do is recursively chmod the subfolders and files of a "root"-folder.
The way I know to do so is:
cd /root-folder
find . -type d -exec chmod 755 {} \;
That will chmod all subfolders from the root-folder to 755.
Next i want
find . -type f -exec chmod 644 {} \;
That will chmod all subfiles fromn the root-folder to 644
Unfortunately, find gives me a permission denied when I run this command from the command-line. When I just manualy chmod everything that works fine but is a bit to much work when it comes down to a tree of 5 subfolders and 120 files.
Waht basically hapens:
The user selects a bunch of folders.
Then they are copied to /Applications/RCT3.localised/Data/Styles/Themed
and then I need to chmod them just to be sure, as sometimes stuff break along the way if you don't
