Regarding the usage of echo: The batch file generated by batch processing always lacks a percent sign - China DOS Union Forum

echo for /L %%i in (1 1 10) do start cmd>>test.bat

I want to put for /L %%i in (1 1 10) do start cmd into test.bat, but actually what is written into test.txt is for /L %i in (1 1 10) do start cmd, always missing a %, please give advice, I'm a newbie.

Strange, this problem seems very simple. According to my idea, it should only generate one %, but I tried it in CMD and found my two %, which is exactly the result you want. What version of Windows do you have?

Do you use 4DOS / 4NT / Take Command? Such a result matches my expectation.

In CMD, it's %%i. In batch processing, it's %%%%i

It should be to add one more % character. Special symbols need to be defined in batch processing. For example, for the "\|" character, if you want to output it, you need to add a "^" character in front.
