查看Linux文件权限号

Question

So I know that ls -l directory will get you the file permssion on a directory...and I know that chmod number directory will change the file permissions on a directory.

But how can I view the number translation of a file permission? I'd like to make an exact copy of a file permission, without making a mistake (I figured it's easy to mess up a number translation of a file permission)

Thanks

(PS I need the number for drwxr-xr-x)

Its just a bit field so its 421 421 421 add up the rwx rwx rwx so in your case

   421
   rwx = 7
   r x = 5
   r x = 5

   755
