1 is standard device output, generally screen output (STDOUT)
2 is error output (ERROUT)
So the above can also be dir 1>nul 2>nul (the reason for not having 1 is that the system defaults to standard output)

So powerful~~~ I'm impressed~ Learned a lot~~ But I still have a question~ That is, the command >nul is to shield the information``Does it execute? What's the difference between it and @echo off???
