You may find the 'find' command more helpful.

For example "find /bin -type d" would list all directories under the
/bin directory (including /bin itself). Used with the (-print0 and
xargs -0) or -exec option, you can then do something on each of these
directories, eg.

find /bin -type d -exec ls -la {} \;
find /bin -type d -print0 | xargs -0 ls -la
