No shell commands are part of the SDK. Using shell commands is likely to result in your app breaking randomly across devices and platform versions.
The recommended way to do this is to write a content provider, which the other app can call ContentResolver.openFileDescriptor() etc. It is actually really easy to write such a content provider -- it doesn't need a database or anything, just to implement ContentProvider.openFile(). Every situation I have seen where MODE_WORLD_* is used it causes more troubles than just writing a content provider. I regret having made that.
