Writing to /dev/null does nothing: data written to this device simply "disappear." Often a command's standard output is silenced by redirecting it to /dev/null, and this is perhaps the null device's commonest use in shell scripting: command > /dev/null. You're using /dev/null differently. You can send output to /dev/null, by using command >/dev/null syntax. However, this will not work when command will use the standard error (FD # 2).

The general form of this one is M>/dev/null, where "M" is a file descriptor number. This will redirect the file descriptor, "M", to /dev/null. 2>&1. The general form of this one is M>&N, where "M" & "N" are file descriptor numbers. It combines the output of file descriptors "M" and "N" into a single stream. |& /dev/null is a special file that’s present in every single Linux system.

/dev/null — специальный файл в системах класса UNIX, представляющий собой так называемое «пустое устройство». Запись в него происходит успешно, независимо от объёма «записанной» информации.

Convert this to the equivalent but rarely-seen form 1>/dev/null. Open /dev/null for output and attach to to file descriptor 1. Note that this overwrites the previous default assignment of stdout done in step (1). Look at the next explicit redirection, '2>/dev/null. Open /dev/null for output and attach that open file to file descriptor 2.

Whatever you write to /dev/null will be discarded, forgotten into the void.
