In Android shell, SH: CP not found

Using the MV command is not feasible for read-only files. If you want to transfer files between your PC and your android target, the easiest way is to use pull or push, if you are copying files in different folders on your android target machine, the simplest method is to use Cat <local >>< remote>, <local> indicates the object to be copied, and <remote> indicates the object to be copied. For example, "Cat test.txt>/sdcard/test.txt", you can copy test.txt under the current folder to/sdcard.
