Where does curl store data whilest it's still downloading

Question

Hi I'm using curl on the command line to automate some downloading of many files from a server . However I'm wondering where curl stores it's data whilst it's downloading?

The reason I need this info is so I can calculate the amount of data been downloaded as a percentage.

Answer 1

While downloading, curl buffers data in the RAM and regularly flushes it to the output (which is probably a file in your case, but may be anything).

Looking at its manual page, I don't see an easy way to get download progress within a script. If you'd provide more details, I'll try to find a solution.

Answer 2

Use -# switch to display the progress bar.
