The first command adjusts directories, the second one adjusts plain files. If you already know that directories have the x bit sets (and plain files don't), you can adjust all the other bits like this:chmod -R u+rw,og=u-w
That last command doesn't use zsh features, so it should work with any standard shell. It adds "rw"to the user's (i.e. owner's) permissions, then copies them to the group's and others' permissions while removing the "w" bit.
