Get octal permissions for files.

Sometimes it would be nice to read the permissions in octal, not only set it in octal.
This can be done using the stat tool.

This command will list all files/folders and their octal permission.

stat -c "%a %n" *

-c is for specifying the display format.
%a is the octal permission and %n is the file name.
