       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.
       It  saves  some  time  at the end because the program does not have to concatenate all the
       downloaded parts.

       Axel supports HTTP, HTTPS, FTP and FTPS protocols.


       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 mirror URLs to an identical file can  be  specified  as  well  and  the
       program will use all those URLs 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.

              Specify  an  alternative  number  of  redirections to follow when connecting to the
              server (default is 20).

       --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  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.

       --ipv6, -6
              Use the IPv6 protocol only when connecting to the host.

       --ipv4, -4
              Use the IPv4 protocol only when connecting to the host.

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

       --insecure, -k
              Do  not  verify  the  SSL certificate. Only use this if you are getting certificate
              errors and you are sure of the sites authenticity.

       --no-clobber, -c Skip download if a file with the same name already exists in the  current
       folder and no state file is found.

       --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.

       --timeout=x, -T x
              Set I/O and connection timeout

       --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.


       The trivial usage to download a file is similar to:

           $ axel

           $ axel

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

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

       This will do a search for the linux-2.4.17.tar.bz2 file on and it'll use
       the  four  (if  possible)  fastest  mirrors   for   the   download   (possibly   including

           $ axel -S4

              Personal configuration file.

       These  files  are  not  documented in a manpage, but the example file which comes with the
       program contains enough information. The position of the  system-wide  configuration  file
       might  be different. In source code this example file is at doc/ directory. It's generally
       installed under /usr/share/doc/axel/examples/, or the equivalent for your system.
