The difference between >/dev/null 2>&1 and 2>&1 >/dev/null and &>/dev/null in the shell

By default, there are always three files open, standard input (keyboard input), standard output (output to screen), standard error (also output to screen), and their respective file descriptors are 0,1,2. So let's take a look at the differences between the following redirection methods:>/dev/null 2>1In fact, it should be equivalent to this: 1>/dev/null 2
