If you want to find out more about how proxies and advanced public data acquisition tools work or about specific web scraping use cases, such as web scraping job postings or building a Python web scraper, check out our blog. ![]() Lastly, the comparison between cURL and Wget overviewed their differences according to the functionality and individual use cases. This article detailed how to configure Wget, from installation and downloading single or multiple files to the methods of using proxies. Select the one that is suitable for your specific scenario at a given moment. Neither tool is decisively better than the other. If you require SOCKS proxy support, pick cURL. For example, if you want recursive downloads, choose Wget. The differences listed above should help you figure out the more suitable tool for a particular scenario. If you want to read about the differences in detail, see the cURL comparison table. More information about what is curl is in this article. This is the most prominent advantage, allowing you to download files recursively using the -mirror switch and create a local copy of a website. Nonetheless, Wget has its advantages as well: Support for more protocols beyond HTTP and FTP ![]() The following features are only available in cURL: Both options:Īre open-source, command-line tools for downloading content from HTTP(S) and FTP(S) cURL vs WgetĬURL or Curl is another open-source command-line tool for downloading files and is available for free.ĬURL and Wget share many similarities, but there are important distinctions differentiating the tools for specific individual purposes.įirst, let’s take a quick look at the similarities. However, it isn’t specific to Wget and will apply to the entire network traffic, making it unsuitable for the task at hand. The proxies can also be set with the environment variables like http_proxy. sig extension, use the following command: These two ensure that no directories are created, and the Wget command doesn’t traverse to a parent directory.įor example, to download all files with the. Some other useful switches are -no-directories and -no-parent. This also takes a list of extensions separated by a comma. Similarly, you may want to download certain files while ignoring everything else by using the -accept switch. Next, you may want to download the files recursively by specifying the -recursive switch.įinally, you may want to skip downloading certain files by specifying the extensions as a comma-separated list to the -reject switch. This behavior can be modified by specifying the -no-clobber switch to skip duplicate files. ![]() It means that for every instance of a compressed.gif file, it’ll create new files with names such as compressed.gif, compressed.gif.1, compressed.gif.2, and so on. If a download results in overwriting a file, it’ll create a new file by appending a numerical suffix. There are multiple reasons for that.īy default, Wget does not overwrite existing files. ![]() However, this command won’t be particularly useful without any further customization. The above is taking the tarball from the "URL" and as it's being downloaded it's being redirected to the command tar so that it can be unpacked into your filesystem.~$ wget -input -file =https : / /ftp. Your command: $ cd ~ & wget -O - "some website leading to the download of a tar file" | tar xzf. In this case that's what they're doing with the | tar xvf. So you can either download the contents of "URL" to a file using -O somefile or you can download it and redirect its contents via STDOUT to another tool to do something with it. Wget -O - > file file will be truncated immediately, andĪll downloaded content will be written there. Of the one in the URL " rather, it is analogous to shell redirection: Use of -O is not intended to mean simply "use the name file instead to print to a file literally named -.) If - is used asįile, documents will be printed to standard output, disabling linkĬonversion. Will be concatenated together and written to file. The documents will not be written to the appropriate files, but all
