使用 set 和 / p 参数，你可以不用换行符来回显：

  C：\> echo Hello World 
 Hello World 

 C：\> echo | set / p =Hello World
 Hello World 
 C：\> 
 

。

What is the Windows batch equivalent of the Linux shell command echo -n which suppresses the newline at the end of the output?

The idea is to write on the same line inside a loop.

Using set and the /p parameter you can echo without newline:

C:\> echo Hello World
Hello World

C:\> echo|set /p="Hello World"
Hello World
C:\>
