Meet axel – it's like a turbo booster for your downloads. Instead of just one connection, it uses several at once to pull files from FTP or HTTP servers, making things much faster. While it's got a bunch of cool tricks up its sleeve, a favorite is -n, where you tell it how many connections to use.

Check out this example: We're using -a for a neat and tidy progress bar and -o to give our downloaded file a fresh new name.

Shoutout to OffSec for the awesome tip!

For those playing close attention, yep, that URL is a sample pen-testing report from the folks at Offensive Security, or as they're now called. Fun fact: I stumbled upon this tool while grinding through my a couple years back.
