Copy To/From SD Card Using Shell

In my root-required android application I need to be able to copy files to and from the SD Card. In most cases root permission is needed. The issue I've come across is that

    cp -fp <source> <destination>

doesn't work when <destination> or <source> contains Environment.getExternalStorageDirectory()

Reading the logs, I noticed that it was failing with No such file or directory

However, when copying to the SD Card, I've ensured that the directory is created in the function before running the command in the shell, and when copying from the SD Card, the file exists.

Is there another way to copy files in the shell (I've tried cp, busybox cp and cat)?

Or is there another way to get the direct path to the location of my files on the SD Card?

Actually managed to solve this mere moments after I asked the question. For information Environment.getExternalStorageDirectory() was returning /storage/emulated/0/

By replacing Environment.getExternalStorageDirectory() with /sdcard/ Everything worked properly.

EDIT 1:
Replacing Environment.getExternalStorageDirectory() with /sdcard/ causes device restrictions (as pointed out by shoe rat below). Sifting through android.os.Environment landed me with another usable alternative System.getenv("EXTERNAL_STORAGE"). Everything still works exactly as it should.
