List All Folders in Linux or Mac
To list all folders, ls provides an option -d. Here is an example.
ls -ld */
The output is
drwxr-xr-x 44 doe staff 1496 Jun 7 20:47 box-folder/
drwxr-xr-x 73 doe staff 2482 Jun 23 17:16 another-folder/
drwxr-xr-x 60 doe staff 2040 Jul 5 15:18 fake-folder-or-not/
In some special cases, a folder might start with -. ls -d -- */ solves the problem. Here -- means the end of the options for ls.
Another choice is tree.
tree -d .
which provides a output of the structures
