I know how ^ is used, but I ran into a problem when I used it. With this line, echo echo 1 ^>1.txt >>2.bat, what shows up in 2.bat is echo 1 >1.txt But with this line, echo 1 ^>>1.txt >>2.bat, what shows up in 2.bat is actually echo 1 > I don't know why replacing > with >> makes it stop working. I searched the forum and didn't find any good answer, so I'd appreciate it if an expert could point it out.

You still haven't really understood the meaning of ^ as an escape symbol;
For special symbols like & ^ > < |, under certain circumstances you need to use ^ to escape them; Each special symbol has to have a ^ added to escape it; So something like >> should be written as ^>^> rather than ^>> |
