AXEL(1)

NAME
Axel - A light download accelerator for Linux.

SYNOPSIS
axel [OPTIONS] url1 [url2] [url...]

DESCRIPTION
Axel is a program that downloads a file from a FTP or HTTP server through multiple connection, each connection downloads its own part of the file. Unlike most other programs, Axel downloads all the data directly to the destination file, using one single thread. It just saves some time at the end because the program doesn't have to concatenate all the downloaded parts.

OPTIONS

One argument is required, the URL to the file you want to download. When downloading from FTP, the filename may contain wildcards and the program will try to resolve the full filename. Multiple URL's can be specified as well and the program will use all those URL's for the download. Please note that the program does not check whether the files are equal.

Other options:

--max-speed=x, -s x
    You can specify a speed (bytes per second) here and Axel will try to keep the average speed around this speed. Useful if you don't want the program to suck up all of your bandwidth.

--num-connections=x, -n x
    You can specify an alternative number of connections here.

--output=x, -o x
    Downloaded data will be put in a local file with the same name, unless you specify a different name using this option. You can specify a directory as well, the program will append the filename.

--search[=x], -S[x]
    Axel can do a search for mirrors using the filesearching.com search engine. This search will be done if you use this option. You can specify how many different mirrors should be used for the download as well. The search for mirrors can be time-consuming because the program tests every server's speed, and it checks whether the file's still available.

--no-proxy, -N
    Don't use any proxy server to download the file. Not possible when a transparent proxy is active somewhere, of course.

--verbose
    If you want to see more status messages, you can use this option. Use it more than once if you want to see more.

--quiet, -q
    No output to stdout.

--alternate, -a
    This will show an alternate progress indicator. A bar displays the progress and status of the different threads, along with current speed and an estimate for the remaining download time.

--help, -h
    A brief summary of all the options.

--version, -V
    Get version information.

NOTE
Long (double dash) options are supported only if your platform knows about the getopt_long call. If it does not (like *BSD), only the short options can be used.

RETURN VALUE
The program returns 0 when the download was succesful, 1 if something really went wrong and 2 if the download was interrupted. If something else comes back, it must be a bug..

EXAMPLES
axel ftp://ftp.{be,nl,uk,de}.kernel.org/pub/linux/kernel/v2.4/linux-2.4.17.tar.bz2
This will use the Belgian, Dutch, English and German kernel.org mirrors to download a Linux 2.4.17 kernel image.
axel -S4 ftp://ftp.kernel.org/pub/linux/kernel/v2.4/linux-2.4.17.tar.bz2
This will do a search for the linux-2.4.17.tar.bz2 file on filesearching.com and it'll use the four (if possible) fastest mirrors for the download. (Possibly including ftp.kernel.org) (Of course, the commands are a single line, but they're too long to fit on one line in this page.)

FILES

/etc/axelrc System-wide configuration file

~/.axelrc Personal configuration file

These files are not documented in a man-page, but the example file which comes with the program contains enough information, I hope. The position of the system-wide configuration file might be different.

BUGS

I'm sure there are some bugs left somewhere, please tell me about them and I will try to fix them. A known bug is that the program does weird things when downloading using hundreds of connections. Well, just don't do that.
