number of directory entries that point to the I node, which can only be deleted if the connection calculation is reduced to 0 o'clock. This is why lifting a connection to a file does not always mean releasing the disk block that the file occupies. This is why the function of deleting a directory entry is called unlink rather than delete.2. Another type of connection is called symbolic connection (symbolic link). The actual content of the symbolic con
