Question

I was looking at some codes, and found this code

{ "su", "-c", "reboot" }

I know that this will make your phone to reboot, because it ask for su first then reboot, but I don’t know what that -c means.

Its like an enter button on the keyboard? also could I add as much ones as I want? something like

{ "su", "-c", "code", "-c", "code", "-c", "code" }

Thanks

Answer 1

-c is a flag that tells the su command to execute the command following -c. So in this case, it is simply, as root, telling the system to reboot.

Some documentation on the su command.
