--progress-bar

Make curl display transfer progress as a simple progress bar instead of the standard, more informational, meter.

This progress bar draws a single line of '#' characters across the screen and shows a percentage if the transfer size is known. For transfers without a known size, there is a space ship (-=o=-) that moves back and forth but only while data is being transferred, with a set of flying hash sign symbols on top.
