How to download multiple files using Wget?
If you need to download multiple files from a website, Wget can be a powerful tool. Here are some options to help you download multiple files at once.
| Option | Description | Example |
|---|---|---|
| -ifile | Downloads URLs listed in a file. Each URL should be on a separate line. | wget -i urls.txt |
| -Apattern | Downloads files that match the specified pattern. The pattern can include wildcards. | wget -A ‘.pdf’ http://example.com/ |
| -r-np | Downloads all files in a directory and its subdirectories. The -np option prevents Wget from ascending to the parent directory. | wget -r -np http://example.com/files/ |
The first option to download multiple files is to create a file containing a list of URLs. You can then use the -i option to download all the files listed in the file. Each URL should be on a separate line in the file.
The second option is to use the -A option to download all files that match a specific pattern. The pattern can include wildcards to match multiple files. For example, -A ‘.pdf’ downloads all files with a .pdf extension.
The third option is to use the -r option to download all files in a directory and its subdirectories. You can also use the -np option to prevent Wget from ascending to the parent directory. For example, -r -np http://example.com/files/ downloads all files in the /files/ directory and its subdirectories, but does not download files from the parent directory.
Step 4: Verify the Download
After downloading your files with Wget, it’s essential to verify that the files you’ve downloaded are complete and error-free. To do this, you can use the md5sum command, which is a cryptographic checksum utility that can verify the integrity of your files.
The md5sum command generates a hash value for the file, which you can compare with the hash value provided by the file’s source. If the hash values match, then the file is error-free, and you can be confident that it has downloaded correctly.
To verify the download, open a terminal window and navigate to the directory where you downloaded the files using the cd command. Then, run the md5sum command followed by the name of the file.
If the hash values match, you’ll see a message that says “OK.” If the hash values don’t match, you’ll need to redownload the file and try again.
Another way to verify your download is to use the sha256sum command, which works similarly to the md5sum command but generates a more secure hash value.
By verifying your downloads using either the md5sum or sha256sum command, you can ensure that your downloaded files are complete and error-free, giving you peace of mind that you have a reliable copy of the files you need.
How to verify the integrity of the downloaded file?
Integrity check: One of the most important things to do after downloading a file is to verify its integrity. To do this, you can use the MD5 or SHA-1 hash values provided by the website you downloaded the file from.
MD5 checksum: To verify the MD5 checksum of the file, open a command prompt, navigate to the folder where the downloaded file is located and type the command “md5sum filename”. The output of this command should match the MD5 checksum provided on the website.
SHA-1 checksum: To verify the SHA-1 checksum of the file, open a command prompt, navigate to the folder where the downloaded file is located and type the command “sha1sum filename”. The output of this command should match the SHA-1 checksum provided on the website.
