Review Summary
Your implementation has critical issues that must be fixed. First, you're not validating that the input contains exactly 3 space-separated elements before accessing indices 1 and 2, which can cause IndexError exceptions with certain inputs — this violates [CHECKLIST ITEM #1]. Add a check like if len(command_splitted) != 3: return before accessing those indices. Second, your exception handling uses f"{Exception}" which only prints the class name instead of the actual error message; use except Exception as e: print(e) instead to get helpful debugging information. These are functional blockers that can cause runtime errors, not just style issues.

The checklist requires checking that the input string contains 3 elements separated by space. Consider validating using len(command_splitted) == 3 before accessing the elements.

Using f"{Exception}" only prints the class name, not the actual error message. Use f"{e}" in an except Exception as e: block instead.

Review Summary
Your implementation passes all requirements. The copy_file function correctly validates input length before accessing indices, checks for the cp command, handles identical source/destination filenames by doing nothing, uses two context managers for reading and writing simultaneously, calls .split() only once, uses double quotes consistently, and implements proper exception handling with except Exception as e: print(e). All checklist items are satisfied, and the code is ready for use.
