如何将变量名称回显到批处理文件，以便目标文件可以使用该变量

Question

I am building a batch file. I want the batch file to be generated, so I echo some lines to a batch file. The problem is the following:

I have generate.bat and backup.bat. When I start generate.bat, I gather some user info and save that to backup.bat. In backup.bat I gather the date and the time. I save that in a variable. How is it possible to save a variable name into that backup.bat, so it can be used in backup.bat

set /P ALOCATION=First loc.%=%
set /P BLOCATION=Second loc. %=%

echo robocopy "%ALOCATION%" "%BLOCATION%%thatpath%" /E /xd "%ALOCATION:~0,3%$Recycle.Bin" >> backup.bat

I already have some code in backup.bat:

SET thatpath=%name%

After this set that I echo the robocopy mentioned above. I, however, want it to use the "thatpath" every time the backup.bat is started.

So to be short: I have a generate.bat, I echo a line to backup.bat, and I would like the line to use a variable in backup.bat. I don't want it to be used in generate.bat, I just want it to be used when starting backup.bat

Answer 1

You can solve this by using echo %%variable%% . It then will be useful for the other batch file.
