how to list current path mode?

Solution 1:

To see the permissions of the current directory, whatever it is, use:

ls -lid .

How it works:

• -l asks ls for a long directory listing.

• -i asks ls for inode information (optional).

• -d tells ls to report on the directory itself, not what is in it.

• . refers, as is conventional for Unix, to the current directory.

Because POSIX ls supports the -l, -i, and -d options, this method is portable.

Solution 2:

Don't use ls at all. It is generally a bad idea to try and parse ls output and there are other tools that are specifically designed for the job. In this case, you can use stat:

$ stat -c '%G %U %y' .

Explanation

   -c  --format=FORMAT
          use the specified FORMAT instead of the default; output  a  new‐
          line after each use of FORMAT

   %G     group name of owner
   %U     user name of owner
   %y     time of last modification, human-readable

So, the command above will print the user (%U), group (%G) and modification time (%y) of ., the current directory. It can also print other pieces of information, pretty much anything you will ever need. See man stat for more.
