title: What do characters like "drwx--xr-x" mean in the output of "ls"?
body: <p>Can someone explain to me what the <code>drwx...</code> lines mean? As I understood starting with <code>d</code> is directory and with <code>-</code> (dash) is a normal file. Can someone confirm and help me understand what files I should create? I am so sorry if this wastes your time but I really got stuck.</p>
