Wget output file12/16/2023 ![]() Imagine, your users are complaining about slow download, and you know their network bandwidth is low. Reducing the bandwidth took longer to download – 28 seconds. Now, let’s try to limit the speed to 500K. It took 0.05 seconds to download 13.92 MB files. ![]() Here is the output of downloading the Nodejs file. Using the -limit-rate option, you can limit the download speed. It would be useful when you want to check how much time your file takes to download at different bandwidth. You just have to ensure giving space between URLs. So, as you can guess, the syntax is as below. Let’s try to download Python 3.8.1 and 3.5.1 files. This can give you an idea about automating files download through some scripts. Handy when you have to download multiple files at once. URL transformed to HTTPS due to an HSTS policy If connectivity is fine, then it will download the homepage and show the output as below. This is very useful as you can use it to download important pages or sites for offline viewing. To do so, it has to download the page recursively. It can follow links in XHTML and HTML pages to create a local version. It can also be used to get the entire website on your local machines. In the background, the wget will run and finish their assigned job. There can be many instances where it is essential for you to disconnect from the system even when doing file retrieval from the web. Wget is non-interactive, which means that you can run it in the background even when you are logged off. Or, you want to download a certain page to verify the content. Or, you want to verify intranet websites. How does wget help you troubleshoot?Īs a sysadmin, most of the time, you’ll be working on a terminal, and when troubleshooting web application related issues, you may not want to check the entire page but just the connectivity. Moreover, you can also use HTTP proxies with it. The wget command supports HTTPS, HTTP, and FTP protocols out of the box. ![]() It is free to use and provides a non-interactive way to download files from the web. Wget command is a popular Unix/Linux command-line utility for fetching the content from the web. ![]() It can be very handy during web-related troubleshooting. Perhaps you should give it a try and see how much slower it really is, starting a new wget process for each URL, instead of using -i and hoping it will be faster, so that you do no have to guess how much slower it is, but just see it.Īlso you could start several wget processes, similar like it can be seen in (just pass more parameters than there), which should speed up everything, for small files.Īnd you still could rename the files after download (also this is not really the way you asked for) to achieve your goal, if you need to construct a list of target file names anyways.One of the frequently used utilities by sysadmin is wget. This tiny bit of time for constructing the command line with parameters won't hurt you, compared with download times.įor the server side it makes no difference at all, if the same or different wget processes do the single requests for files, which are done in both scenarios, the tiny bit off Keep-Alive won't make much difference, in my opinon.īy the way: wget is always single threaded, there is no parameter to make it multi-threaded. Just loop through the file line by line, read the line contents into variable FOO and use that as wget parameter: while read FOO do echo wget $FOO done < filelist.txt
