Wget download certain file from website

If it returns an index page without any of the mentioned files, wget can magically get them. I think that an option -nd also will be useful here. It allows to download matched files to the current directory without creating a hierarchy of directories. Therefore if you have your own website you can make a complete backup using this one simple command. You can get wget to run as a background command leaving you able to get on with your work in the terminal window whilst the files download.
You can of course combine switches. To run the wget command in the background whilst mirroring the site you would use the following command:.
If you are running the wget command in the background you won't see any of the normal messages that it sends to the screen. You can get all of those messages sent to a log file so that you can check on progress at any time using the tail command.
To output information from the wget command to a log file use the following command:. The reverse, of course, is to require no logging at all and no output to the screen. To omit all output use the following command:. Open up a file using your favorite editor or even the cat command and simply start listing the sites or links to download from on each line of the file.
Apart from backing up your own website or maybe finding something to download to read on the train, it is unlikely that you will want to download an entire website. You are more likely to download a single URL with images or perhaps download files such as zip files, ISO files or image files. With that in mind you don't want to have to type the following into the input file as it is time consuming:. If you know the base URL is always going to be the same you can just specify the following in the input file:.
If you have set up a queue of files to download within an input file and you leave your computer running all night to download the files you will be fairly annoyed when you come down in the morning to find that it got stuck on the first file and has been retrying all night.
You might wish to use the above command in conjunction with the -T switch which allows you to specify a timeout in seconds as follows:. The above command will retry 10 times and will try to connect for 10 seconds for each link in the file. You can use wget to retry from where it stopped downloading by using the following command:.
If you are hammering a server the host might not like it too much and might either block or just kill your requests. You can specify a wait period which specifies how long to wait between each retrieval as follows:.
The above command will wait 60 seconds between each download. 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.
In circumstances such as this, you will usually have a file with the list of files to download inside. An example of how this command will look when checking for a list of files is:. If you want to copy an entire website you will need to use the --mirror option.
As this can be a complicated task there are other options you may need to use such as -p , -P , --convert-links , --reject and --user-agent. It is always best to ask permission before downloading a site belonging to someone else and even if you have permission it is always good to play nice with their server. If you want to download a file via FTP and a username and password is required, then you will need to use the --ftp-user and --ftp-password options.
If you are getting failures during a download, you can use the -t option to set the number of retries. This user had a similar problem and it seems he's solved it. Show 1 more comment.
