| # PROGRESS METER | |
| curl normally displays a progress meter during operations, indicating the | |
| amount of transferred data, transfer speeds and estimated time left, etc. The | |
| progress meter displays the transfer rate in bytes per second. The suffixes | |
| (k, M, G, T, P) are 1024 based. For example 1k is 1024 bytes. 1M is 1048576 | |
| bytes. | |
| curl displays this data to the terminal by default, so if you invoke curl to | |
| do an operation and it is about to write data to the terminal, it *disables* | |
| the progress meter as otherwise it would mess up the output mixing progress | |
| meter and response data. | |
| If you want a progress meter for HTTP POST or PUT requests, you need to | |
| redirect the response output to a file, using shell redirect (\>), --output | |
| or similar. | |
| This does not apply to FTP upload as that operation does not spit out any | |
| response data to the terminal. | |
| If you prefer a progress bar instead of the regular meter, --progress-bar is | |
| your friend. You can also disable the progress meter completely with the | |
| --silent option. | |
