axel - light command line download accelerator


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


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 does not
have to concatenate all the downloaded parts.


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
Specify a speed (bytes per second) to try to keep the average speed around this
speed. This is useful if you do not want the program to suck up all of your

--num-connections=x, -n x
Specify an alternative number of connections.

--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
Do not use any proxy server to download the file. Not possible when a transparent
proxy is active somewhere, of course.

--verbose, -v
Show more status messages. Use it more than once to see more details.

--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.

--header=x, -H x
Add an additional HTTP header. This option should be in the form "Header: Value".
See RFC 2616 section 4.2 and 14 for details on the format and standardized headers.

--user-agent=x, -U x
Set the HTTP user agent to use. Some websites serve different content based upon
this parameter. The default value will include "Axel", its version and the

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

--version, -V
Get version information.


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.


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


This will use the Belgian, Dutch, English and German kernel.org mirrors to download a
Linux 2.4.17 kernel image.

axel ftp://ftp.{be,nl,uk,de}.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.

axel -S4 ftp://ftp.kernel.org/pub/linux/kernel/v2.4/linux-2.4.17.tar.bz2
