Well, if your phone is rooted you can run commands with the su -c
command.
Here is an example of a cat
command on the build.prop
file to get a phone's product information.
adb shell "su -c 'cat /system/build.prop |grep "product"'"
This invokes root permission and runs the command inside the ' '
.
Notice the 5 end quotes, that is required that you close ALL your end quotes or you will get an error.
For clarification the format is like this.
adb shell "su -c '[your command goes here]'"
Make sure you enter the command EXACTLY the way that you normally would when running it in shell.
