ping -n 2 127.1>nul
I don't understand!!
I'm a newbie, and please各位 experts teach me what it means, please!!
Excuse me!!

Modified title: What does ping -n 2 127.1>nul mean
Explanation: Because the original title was too vague, which was not convenient for forum search and management. Three days after this notice was posted,
　　the original poster had not changed the title. Now I forcefully modify the title and deduct 2 points from the original poster's points.
