Chmod, linuxchmod

When using chmod-R o + rx/data, you set the execute permission on all directories as well as files in the/data directory.

To set the execute permission to directories only, and not to files, use chmod-R o + rX/data. the uppercase X ensures that files will not get the execute permission unless the file has already set the execute permission for some of the entities. that makes X the more intelligent way of dealing with execute permissions; it will avoid setting that permission on files where it is not needed.
