chmod question

[z-vet]

Hi all.
I need to change permission for directory and it´s subdirs. Running ´chmod -R a+x some_dir´ changing permissions for all of this directory´s content, including files. How can i change permissions for directory and subdirectories but leave a permissions for files unchanged?

You could use find:

find ./ -type d -print0 | xargs -0 chmod perms

Or, if you don't want to grant execute on files (unless they already have it) use a+X.
