Why are you running `sudo adb shell [...]`? I would guess you want `adb shell su root [...]`.

[jeff shanab]

is it saying you cannot run bash? or is it saying bash cannot run hi

Here's a more practical version; L$ is the Linux shell prompt, A$ is the Android shell prompt.

L$ adb push /home/hi /data/local/tmp                    # /data/local/tmp is a directory on device internal storage, where the  

                                                                             # execute bit in file permissions survives pushing to the device.

L$ adb shell

A$ cd /data/local/tmp

A$ ls -l hi

A$ ./hi

Is /home/hi an Android binary? What does it say when you run "file /home/hi"?

this includes /sdcard and other mount links to internal/external storage
