Aria2 usage example

Here are some uses of the Aria2 command line tool.

1. Download a single file through the network

Syntax:

# aria2c URL

Download QQ for Linux as an example and run the following command:

[root@localhost ~] # aria2c http://down.qq.com/qqweb/LinuxQQ/linuxqq_2.0.0-b2-1084_x86_64.rpm

2. Save the file under a different name after download

To save the file under a different name, use the-o option, as shown below, and change the file name to linux-qq.rpm:

[root@localhost] # aria2c-o linux-qq.rpm http://down.qq.com/qqweb/LinuxQQ/linuxqq_2.0.0-b2-1084_x86_64.rpm

3. Download multiple files

To download multiple files, use the-Z option, followed by the URL address where you want to download the file, and the following example downloads the linux version of qq and the linux version of the sunflower command line client.

[root@localhost ~] # aria2c-Z linux-qq.rpm http://down.qq.com/qqweb/LinuxQQ/linuxqq_2.0.0-b2-1084_x86_64.rpm https://down.oray.com/sunlogin/linux/sunloginclientshell-10.1.1.28779.x86_64.rpm

4. Download files from the list

You can create a file that lists all files URL instead of listing all file URL addresses on the terminal. You can use the-I option. The following example downloads multiple files. First, take a look at the file where the url address is stored:

[root@localhost ~] # cat pic_download.txt https://www.linuxprobe.com/wp-content/uploads/2021/01/windows7.pnghttps://www.linuxprobe.com/wp-content/uploads/2016/12/bigdata.jpghttps://www.linuxprobe.com/wp-content/uploads/2021/01/write-games-and-learn-python.jpghttps://www.linuxprobe.com/wp-content/uploads/2021/01/data-center-inspection.jpghttps://www.linuxprobe .com / wp-content/uploads/2020/03/devolop-like-linux-09.jpg

Then use the-I option to download:

[root@localhost] # aria2c-I pic_download.txt

5. Limit the download speed

By default, aria2 uses the maximum bandwidth to download files. You can use the-- max-download-limit option to limit bandwidth, and the download speed is limited to 100K below. :

[root@localhost ~] # aria2c-- max-download-limit=100K http://down.qq.com/qqweb/LinuxQQ/linuxqq_2.0.0-b2-1084_x86_64.rpm

6. Breakpoint continuation

You can use the-c option to continue downloading files that have not been downloaded:

[root@localhost] # aria2c-c-- max-download-limit=100K http://down.qq.com/qqweb/LinuxQQ/linuxqq_2.0.0-b2-1084_x86_64.rpm

Currently this option is only available for HTTP (S) / FTP downloads.

7. Download the magnetic link file

To download a magnetic link file, if there is no speed to download, you can add the-bt-tracker= option, followed by the address of tracker, followed by the BT seed or magnetic link address:

[root@localhost ~] # aria2c-- bt-tracker=udp://tracker.opentrackr.org:1337/announce,udp://tracker.cyberia.is:6969/announce,udp://exodus.desync.com:6969/announce,udp://3rt.tace.ru:60889/announce, http://5rt.tace.ru:60889/announce, Udp://tracker.internetwarriors.net:1337/announce magnet:?xt=urn:btih:45521E5D3C26890BAAA2928BC511D1BE88074518&dn=cn_windows_10_business_editions_version_20h3_updated_dec_2020_x64_dvd_547eb680.iso&xl=5982177280

As you can see, the download speed is still very fast.

The Tips:Tracker address is in github. If there is no speed, you can change several tracker addresses. Https://github.com/ngosang/trackerslist/blob/master/trackers_best.txt . Each address is separated by a comma.
