    -print is the default. "." is also the default directory. So you can get away with
    Code:
    find -type d
    ("d" means of type "directory") or
    Code:
    find path -type d
    Note that find is recursive -- it will show you subdirectories and so on too. If you just want a list of directories in the current directory, you can use something like this.
    Code:
    ls -l | grep ^d
    That gives you the long filename listing, however, which you may not want. If you just want the filenames, you could use something like this:
    Code:
    for file in *; do [ -d "$file" ] && echo $file; done
    I'm sure there's a cleaner way, but if there is, it escapes me at the moment.
