- Copy a directory recursively, in verbose mode (shows files as they are copied):                                                                                        
                                                                                                                                                                         
  cp -vr path/to/directory path/to/copy                                                                                                                                  
                                                                                                                                                                         
- Copy text files to another location, in interactive mode (prompts user before overwriting):                                                                            
                                                                                                                                                                         
  cp -i *.txt path/to/target_directory
