You can specify the number of retries using the following switch:. Use the above command in conjunction with the -T switch to specify a timeout in seconds, as follows:. The above command will retry 10 times and connect for 10 seconds for each file link. To use wget to retry from where it stopped downloading, use the following command:. If you hammer a server, the host might not like it and might block or kill your requests. You can specify a waiting period to specify how long to wait between each retrieval, as follows:.
The above command waits 60 seconds between each download. This is useful if you download many files from a single source. Some web hosts might spot the frequency and block you. You can make the waiting period random to make it look like you aren't using a program, as follows:.
Many internet service providers apply download limits for broadband usage, especially for those who live outside of a city. You may want to add a quota so that you don't go over your download limit. You can do that in the following way:. The -q command won't work with a single file.
If you download a file that is 2 gigabytes in size, using -q m doesn't stop the file from downloading. The quota is only applied when recursively downloading from a site or when using an input file. Some sites require you to log in to access the content you wish to download. Use the following switches to specify the username and password.
On a multi-user system, when someone runs the ps command, they can see your username and password. By default, the -r switch recursively downloads the content and creates directories as it goes. To get all the files to download to a single folder, use the following switch:. The opposite of this is to force the creation of directories, which can be achieved using the following command:.
If you want to download recursively from a site, but you only want to download a specific file type such as an MP3 or an image such as a PNG, use the following syntax:. The reverse of this is to ignore certain files. Perhaps you don't want to download executables. In this case, use the following syntax:. There is a Firefox add-on called cliget. To add this to Firefox:. Click the install button when it appears, and then restart Firefox. To use cliget, visit a page or file you wish to download and right-click.
A context menu appears called cliget, and there are options to copy to wget and copy to curl. Click the copy to wget option, open a terminal window, then right-click and choose paste. The appropriate wget command is pasted into the window. This saves you from having to type the command yourself. The wget command has several options and switches. To read the manual page for wget, type the following in a terminal window:. The wget command is an internet file downloader that can download anything from files and web pages all the way through to entire websites.
This will download the filename. The -O option sets the output file name. If the file was called filename If you want to download a large file and close your connection to the server you can use the command:. If you want to download multiple files you can create a text file with the list of target files.
Each filename should be on its own line. You would then run the command:. You can also do this with an HTML file. If you have an HTML file on your server and you want to download all the links within that page you need add --force-html to your command.
Usually, you want your downloads to be as fast as possible. However, if you want to continue working while downloading, you want the speed to be throttled. If you are downloading a large file and it fails part way through, you can continue the download in most cases by using the -c option.
Normally when you restart a download of the same filename, it will append a number starting with. If you want to schedule a large download ahead of time, it is worth checking that the remote files exist. The option to run a check on files is --spider. Of course, and all internal links will convert to relative links. The latter is vital to have a browsable offline copy, while excluded or external links remain unchanged. The described method uses front-end crawling, much like what a search engine does.
The mere fact that a blogger is using some standard WordPress widgets in the sidebar like the monthly archive or a tag cloud helps bots tremendously. While the subculture that uses wget daily is heavily weighted towards Unix, using wget on Windows is a bit more unusual.
The average Windows user wants the binaries , therefore:. If you try to open the. I want to access this wget. The longer name is probably more meaningful and recognizable. Check the official description of these settings if you wish, as here I only share my opinion and why I chose them.
In the order of importance, here they are. This is a bundle of specific other settings, all you need to know that this is the magic word that enables infinite recursion crawling.
Sounds fancy? Because it is! This makes it possible to browse your archive locally. It affects every link that points to a page that gets downloaded. Imagine that you went out of your way to download an entire website, only to end up with unusable data. Unless the files end in their natural extensions, you or your browser is unable to open them. This setting helps you open the pages without hosting the archive on a server.
Unless you use the next setting, content sent via gzip might end up with a pretty unusable. Combine with the previous setting. Note that if you use Unix, this switch might be missing from your wget, even if you use the latest version.

You can reject any URL containing certain words to prevent certain parts of the site from being downloaded. For me, it generated too long filenames, and the whole thing froze.
This prevents some headaches when you only care about downloading the entire site without being logged in. Some hosts might detect that you use wget to download an entire website and block you outright. Spoofing the User Agent is nice to disguise this procedure as a regular Chrome user.
If the site blocks your IP, the next step would be continuing things through a VPN and using multiple virtual machines to download stratified parts of the target site ouch. You might want to check out --wait and --random-wait options if your server is smart, and you need to slow down and delay requests. On Windows, this is automatically used to limit the characters of the archive files to Windows-safe ones.
However, if you are running this on Unix, but plan to browse later on Windows, then you want to use this setting explicitly. Unix is more forgiving for special characters in file names. There are multiple ways to achieve this, starting with the most standard way:. If you want to learn how cd works, type help cd to the prompt. Once I combine all the options, I have this monster.
