You can download a single file, multiple files, entire directory or even an entire website using wget. + +wget is non-interactive and can easily work in the background. This means you can easily use it in scripts or even build tools like [uGet download manager][3]. + +Let’s see how to use wget to download file from terminal. + +#### Installing wget + +Most Linux distributions come with wget preinstalled. It is also available in the repository of most distributions and you can easily install it using your distribution’s package manager. + +On Ubuntu and Debian based distribution, you can use the [apt package manager][4] command: + +``` +sudo apt install wget +``` + +#### Download a file or webpage using wget + +You just need to provide the URL of the file or webpage. It will download the file with its original name in the directory you are in. + +``` +wget URL +``` + +![][5] + +To download multiple files, you’ll have to save their URLs in a text file and provide that text file as input to wget like this: + +``` +wget -i download_files.txt +``` + +#### Download files with a different name using wget + +You’ll notice that a webpage is almost always saved as index.html with wget. It will be a good idea to provide custom name to downloaded file. + +You can use the -O (uppercase O) option to provide the output filename while downloading. + +``` +wget -O filename URL +``` + +![][6] + +#### Download a folder using wget + +Suppose you are browsing an FTP server and you need to download an entire directory, you can use the recursive option + +``` +wget -r ftp://server-address.com/directory +``` + +#### Download an entire website using wget + +Yes, you can totally do that. You can mirror an entire website with wget. By downloading an entire website I mean the entire public facing website structure. + +While you can use the mirror option -m directly, it will be a good idea add: + + * –convert-links : links are converted so that internal links are pointed to downloaded resource instead of web + * –page-requisites: downloads additional things like style sheets so that the pages look better offline + + + +``` +wget -m --convert-links --page-requisites website_address +``` + +![][7] + +#### Bonus Tip: Resume incomplete downloads + +If you aborted the download by pressing C for some reasons, you can resume the previous download with option -c. + +``` +wget -c +``` + +### Download files from Linux command line using curl + +Like wget, [curl][8] is also one of the most popular commands to download files in Linux terminal. There are so many ways to [use curl extensively][9] but I’ll focus on only the simple downloading here. + +#### Installing curl + +Though curl doesn’t come preinstalled, it is available in the official repositories of most distributions. You can use your distribution’s package manager to install it. + +To [install curl on Ubuntu][10] and other Debian based distributions, use the following command: + +``` +sudo apt install curl +``` + +#### Download files or webpage using curl + +If you use curl without any option with a URL, it will read the file and print it on the terminal screen. + +To download a file using curl command in Linux terminal, you’ll have to use the -O (uppercase O) option: + +``` +curl -O URL +``` + +![][11] + +It is simpler to download multiple files in Linux with curl. You just have to specify multiple URLs: + +``` +curl -O URL1 URL2 URL3 +``` + +Keep in mind that curl is not as simple as wget. While wget saves webpages as index.html, curl will complain of remote file not having a name for webpages. You’ll have to save it with a custom name as described in the next section. + +#### Download files with a different name + +It could be confusing but to provide a custom name for the downloaded file (instead of the original source name), you’ll have to use -o (lowercase O) option: + +``` +curl -o filename URL +``` + +![][12] + +Some times, curl wouldn’t just download the file as you expect it to. You’ll have to use option -L (for location) to download it correctly. This is because some times the links redirect to some other link and with option -L, it follows the final link. + +#### Pause and resume download with curl + +Like wget, you can also resume a paused download using curl with option -c: + +``` +curl -c URL +``` + +**Conclusion** + +As always, there are multiple ways to do the same thing in Linux. Downloading files from the terminal is no different. + +wget and curl are just two of the most popular commands for downloading files in Linux. There are more such command line tools. Terminal based web-browsers like [elinks][13], [w3m][14] etc can also be used for downloading files in command line. + +Personally, for a simple download, I prefer using wget over curl. It is simpler and less confusing because you may have a difficult time figuring out why curl could not download a file in the expected format. + +Your feedback and suggestions are welcome. + +-------------------------------------------------------------------------------- + +via: https://itsfoss.com/download-files-from-linux-terminal/ + +作者：[Abhishek Prakash][a] +选题：[lujun9972][b] +译者：[译者ID](https://github.com/译者ID) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]: https://itsfoss.com/author/abhishek/ +[b]: https://github.com/lujun9972 +[1]: https://i1.wp.com/itsfoss.com/wp-content/uploads/2020/10/Download-Files-from-Linux-terminal.png?resize=800%2C450&ssl=1 +[2]: https://www.gnu.org/software/wget/ +[3]: https://itsfoss.com/install-latest-uget-ubuntu-linux-mint/ +[4]: https://itsfoss.com/apt-command-guide/ +[5]: https://i0.wp.com/itsfoss.com/wp-content/uploads/2020/10/download-file-in-linux-terminal-using-wget.png?resize=795%2C418&ssl=1 +[6]: https://i2.wp.com/itsfoss.com/wp-content/uploads/2020/10/download-file-in-linux-terminal-using-wget-2.png?resize=795%2C418&ssl=1 +[7]: https://i1.wp.com/itsfoss.com/wp-content/uploads/2020/10/download-entire-website-using-wget.png?resize=795%2C418&ssl=1 +[8]: https://curl.haxx.se/ +[9]: https://linuxhandbook.com/curl-command-examples/ +[10]: https://itsfoss.com/install-curl-ubuntu/ +[11]: https://i0.wp.com/itsfoss.com/wp-content/uploads/2020/10/download-files-in-linux-using-curl.png?resize=795%2C418&ssl=1 +[12]: https://i2.wp.com/itsfoss.com/wp-content/uploads/2020/10/download-files-in-linux-using-curl-1.png?resize=795%2C418&ssl=1 +[13]: http://elinks.or.cz/ +[14]: http://w3m.sourceforge.net/
