title: How can be the variables change in other file? batch file
body: <p>So here is what I need , I have two files , the first one is this:
  1)</p>
  
  <pre><code>set idVendor=3edd
  </code></pre>
  
  <p>In the second file is this:
  2)</p>
  
  <pre><code>   write /sys/class/android_usb/android0/enable 0
  write /sys/class/android_usb/android0/idVendor %idVendor%
  write /sys/class/android_usb/android0/idProduct 4EE2
  write /sys/class/android_usb/android0/functions mtp,adb
  write /sys/class/android_usb/android0/iManufacturer ${ro.product.manufacturer}
  write /sys/class/android_usb/android0/iProduct ${ro.product.model}
  write /sys/class/android_usb/android0/iSerial ${ro.serialno}
  </code></pre>
  
  <p>So I want to replace %idVendor% with 3edd , but in the other file </p>
  
  <p>NOTE:
  the other file is not a bat file</p>
