Eval script containing PATH in Windows CMD

Question

I need to eval the commands thrown by some command 'minishift oc-env' which has PATH in it.

However, it seems that it is overwriting the whole PATH variable.

C:\Users\budhram>echo %PATH%
C:\Program Files\Docker\Docker\Resources\bin;C:\Users\budhram\AppData\Local\Temp;C:\ProgramData\Oracle\Java\javapath;C:\WINDOWS\system32;C:\WINDOWS;.....

C:\Users\budhram>minishift oc-env
SET PATH=C:\Users\budhram\.minishift\cache\oc\v1.5.0;%PATH%;
REM Run this command to configure your shell:
REM     @FOR /f "tokens=*" %i IN ('minishift oc-env') DO @%i

C:\Users\budhram>SET PATH=C:\Users\budhram\.minishift\cache\oc\v1.5.0;%PATH%;

C:\Users\budhram>echo %PATH%
C:\Users\budhram\.minishift\cache\oc\v1.5.0;C:\Program Files\Docker\Docker\Resources\bin;C:\Users\budhram\AppData\Local\Temp;C:\ProgramData\Oracle\Java\javapath;C:\WINDOWS\system32;C:\WINDOWS;....

C:\Users\budhram>@FOR /f "tokens=*" %i IN ('minishift oc-env') DO @%i

C:\Users\budhram>echo %PATH%
C:\Users\budhram\.minishift\cache\oc\v1.5.0;%PATH%;

Any idea how we can do that?
This answer https://stackoverflow.com/a/9370376/1120530 also suggest about using setlocal enableDelayedExpansion which seems to be not working in my case.

When you run

@FOR /f "tokens=*" %i IN ('minishift oc-env') DO @%i

the do clause will execute

SET PATH=C:\Users\budhram\.minishift\cache\oc\v1.5.0;%PATH%;

which seems correct, BUT the problem is that after %i has been expanded to the indicated command, there is not a second expansion to convert %PATH% to the value in the variable.

You can try with

@FOR /f "tokens=*" %i IN ('minishift oc-env') DO @call %i

where the call command will force a second parse phase that will expand the %PATH% reference.
