Progress meter

                              curl has a built-in progress meter. When
                                    curl is invoked to transfer data (either
                                    uploading or downloading) it can show that
                                    meter in the terminal screen to show how the
                                    transfer is progressing, namely the current
                                    transfer speed, how long it has been going
                                    on and how long it thinks it might be left
                                    until completion.
                            
                              The progress meter is inhibited if curl
                                    deems that there is output going to the
                                    terminal, as the progress meter would
                                    interfere with that output and just mess up
                                    what gets displayed. A user can also
                                    forcibly switch off the progress meter with
                                    the -s / --silent
                                    option, which tells curl to hush.
                            
                              If you invoke curl and do not get the
                                    progress meter, make sure your output is
                                    directed somewhere other than the
                                    terminal.
                            
                              curl also features an alternative and
                                    simpler progress meter that you enable with -# / --progress-bar. As the long name implies, it instead
                                    shows the transfer as progress bar.
                            
                              At times when curl is asked to transfer
                                    data, it cannot figure out the total size of
                                    the requested operation and that then
                                    subsequently makes the progress meter
                                    contain fewer details and it cannot, for
                                    example, make forecasts for transfer times,
                                    etc.

                              The progress meter displays bytes and bytes
                                    per second.
                            
                              It will also use suffixes for larger
                                    amounts of bytes, using the 1024 base system
                                    so 1024 is one kilobyte (1K), 2048 is 2K,
                                    etc. curl supports these:
