This is a pure Linux Terminal This goes to the heart of Linux. If you HAVE root you can add commands with symbolic links to busybox or toolbox. Simply make a symbolic link the busybox or toolbox binary and give it the name of the command you want to add. ln - s cp busybox in the directory where busybox is creates the cp command. ln -s mkdir toolbox in the directory where toolbox is creates the mkdir command. (Note: Not all commands are supported so it doesn't always work.) (Note2: Symbolic links are not supported by the filesystem on the user's sdcard. If they were you could make symbolic links there.)
