command line - CMD batch escaping environment variable in params

I have to write a batch file with a environment variable a param:

c:\myapp.exe -f "%APP_HOME%\file.conf" 

I need to pass exactly the string %APP_HOME% as param and not its value. How can I do?

In other words, I don't want to strip the variable in the batch runtime but I would like to let the application use it as parametrized path, if I change this environment variable I don't want to change the variable in the application.

Answer

I need to pass exactly the string "%APP_HOME% as param

1. Replace % with ^%



2. Remove the "s

   
   
   

   c:\myapp.exe -f ^%APP_HOME^%\file.conf

test.cmd:

@echo %1 %2 %3

output:

F:\test>test c:\myapp.exe -f ^%APP_HOME^%\file.conf
c:\myapp.exe -f %APP_HOME%\file.conf
F:\test>
