Linux multi-threaded download tool Axel

Generally, under Linux we are accustomed to download with wget, but the disadvantage of the tool is that it is not possible to do multi-threaded download, so often sometimes not fast enough.
The Axel introduced here is Linux's next good HTTP or FTP high-speed download tool. Support multi-threaded download, breakpoint continuation, and can be from multiple addresses or multiple connections from one address to download the same file, suitable for the speed of the multi-threaded download to improve download speed. It is important to note that the software has only a command-line interface.
