Ways to make only dirs executable WITOUT using find

Often, I find myself needing to make a tree of directories executable for someone, ie:

find . -type d -exec chmod ug+x {} \;

But I don't like the overhead of find, and running a "new"chmod for every dir.

You folks have preferred alternatives?

have u tried chmod -R?

chmod -R will make ALL files executable, I only want the x bit set in directories.
chmod -RX . is a better, but only if none of the regular files have any of thier x bits set. The best I have found is:

Code:

---

find . -type d -exec chmod ug+x {} +

---

This variant of the -exec action runs the specified command on the selected files, but the command line is built by appending each selected file name at the end; the total number of invocations of the command will be much less than the number of matched files.

what about just calling one chmod on the output of the find command? e.g.:

Code:

---

chmod +x `find . -type d whatever`

---

does that do what u want? I've never used the '+' with find before...
