How can I run Linux commands on an Android device?

Question

On some Android devices, in the ADB shell, I can only run echo, cd, ls. When I run:

tar -cvf //mnt/sdcard/BackUp1669/a         


        

Answer 1

If you have the binaries for your system, you can run anything on your system.

Saying that you have to understand that you have to find the binaries for tar.
