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. The problem with this solution is that identify is actually accepting my partially downloaded images. I'm not sure why, but it does and then attempts to pass them to convert which returns convert: corrupt image 2.

Below, you can see that instead of writing options separately -d -r -c , you can combine them in this format -drc.
Rather than just a single web page, you may also want to download an entire website to see how the website is built. Wget downloads all the files that make up the entire website to the local-dir folder, as shown below. The command below outputs the same result as the previous one you executed. The difference is that the --wait option sets a second interval in downloading each web page. While the --limit option sets the download speed limit to 50K mbps. As you did in the previous examples, downloading files manually each day is obviously a tedious task.
Wget offers the flexibility to download files from multiple URLs with a single command, requiring a single text file. Open your favorite text editor and put in the URLs of the files you wish to download, each on a new line, like the image below.
By now, you already know your way of downloading files with the wget command. But perhaps, your download was interrupted during the download. What would you do? Another great feature of wget is the flexibility to resume an interrupted or failed download.
Below is an example of an interrupted download as you lost your internet connection. The download progress will automatically resume when you get your internet connection back.
