Correct command for root access in Android

Question

I have next example:

RootTools.isRootAvailable()
Command command = new Command(0, "echo this is a command", "echo this is another command");
try {
    RootTools.getShell(true).add(command);
}catch (IOException | RootDeniedException | TimeoutException ex) {
    ex.printStackTrace();
}

But i don't know what to write to "echo this is a command", "echo this is another command" and how to apply it for my folder without permission. Maybe you know? Thanks.

Answer 1

This placeholder this is a command should be replaced with bash code.

You (most likely, assuming it's not specific to Android) could run it in a Linux terminal.

The placholder echo this is a command is a perfectly valid command, and will simply echo, or print the text.

Some other command you could run are:

1. cp copy file
2. mv move file
3. touch create an empty file
