chmod to only change permissions of directories

Hello everyone.
I am in need of a command (or even shell or perl script) that will allow me to recursively (-R) change the permissions on only directories, leaving existing regular file permissions alone. I will also need to then change only the file permissions, leaving the directory permissions in place.

In the end, I will need to list (ls) only directories, and then only files.

My need for this is to change all directory permissions to 755, while changing all files to 555 within a large directory structure (in a Linux and HP 11.x environment).

Errmm.. a simple find and -exec would do the trick perhaps..

find /path-here-of-directories-you-want-to-change/ -type d -exec chmod 755 {} \;

Perhaps that'll get you started.. man find for more details, options, etc.

useful commands

Thanks for the help. Here are the commands that I ended putting together in the end:

This command will recursively change all directories that are 777 for example, to 775:
find path/ -perm 777 -type d -exec chmod 775 {} \;

This command will recursively change all files that are 777 to 775:
find path/ -perm 777 -type f -exec chmod 775 {} \;
