See for Axel's new home. Giridhar Appaji Nag Y will take over Axel development from me. I don't use the program myself anymore for ages, so I'm sure he'll be a better maintainer than I was.

Axel does the same thing any other accelerator does: it opens more than one HTTP/FTP connection per download and each connection transfers its own, separate, part of the file. It may sound weird, but it works very well in practice. For example, some FTP sites limit the speed of each connection, therefore opening more than one connection at a time multiplies the allowable bandwidth. Be forewarned that some FTP operators don't like it when you do this. It is better to open the additional connections on several servers and download from all of them simultaneously. Axel >=0.97 supports this. You may either specify a list of mirrors to use or tell the program to search for mirrors.

The difference between Axel and other (mostly Windows-based) accelerators is that it does not write data to separate files and join them later. Axel puts all the data in the right file, in the right order, at download time. This is possible, because most Unix file systems allow you to write data after the end-of-file. Axel is console-based and uses few system resources.

Supported architectures


Current version: Axel 1.0b

There's a kaptain grammar file for Axel as well. There's a separate .rpm package for it, or you can find it in the source tarball.

If you really want a non-threaded version, you can download the 0.96b version instead. It's not really supported anymore, but it might be useful on systems which don't support pthreads.
