Permission Block

Definition: Permission Block: This is part of the inode table's entries for each file and directory. The permission block can be shown for files and directores by using "ls -al" - the long output directory listing and is represented by 10 characters. The first character is a file type indicator differentiating between a file and a directory. The other nine characters refer to access permissions for the owner, group and world.
