“>” means that it will cover the content. The original content is gone.
“>” means that it will add the content to the file. The original content is still there.

Note:
1. There is a space between key words. For example, for /L %%a in (1, 1 10) do (). It must have a space between “in” and “(“.

for /L %%a in (1, 1, 10) do (
    echo %%a
