It is easy to download a file with a download manager. Through a graphical user interface, users can download many files. But if we talk about the command-line interface or the terminal, most users find it difficult to use this environment. An inexperienced user cannot even download files through a Linux terminal without the assistance of an internet or expert user. Many download managers are used to downloading files from a Linux or Unix environment. In this article, we will explore how we can download files using the wget command in the Rocky Linux Terminal.
Wget is a freely available command-line utility for downloading files. This tool can be installed on Linux, Unix, Windows as well as Mac OS. It is a non-interactive package that allows us to download files in the background without interrupting our work. The program supports downloading files over common web protocols such as HTTP, FTP, and HTTPS. Wget offers the following features:
Robustness – it can work even if the Internet connection is slow or unstable.
Wget continues downloading files when downloading is interrupted due to Internet problems.
It is used to download files recursively from the Internet.
Check the installed wget version
You can check which version of wget is installed on your system. Use the following command.
Install Wget command
If wget is not installed then you will install using dnf command as given below.
$dnf -y install wget
here, -y option is used for confirmation before installing any utility.
There are the following ways through which we can download files through the wget package.
Download a Single file
When you are downloading a single file, then type wget command and will give the absolute path of file destination.
$ wget https://www.somedomain.tld/somefile.txt
Rename to the download file
You can save the downloaded file with a different name. Type wget -O to rename a file. We have renamed with wgetgetfilesam.zip as shown below.
$ wget -O website URL
$ wget -O /tmp/testfile.zip https://somedomain.tld/otherfile.zip
This command will download the file https://somedomain.tld/otherfile.zip and save it as testfile.zip in the /tmp folder of the local system.
Download the file into a specific directory
You can save the downloaded file into a particular folder or directory. Type the wget command with -P directory name where you want to save the file and type the URL of the file path. As shown below.
$ wget -P <directory path> <website URL>
$ wget -P /tmp https://somedomain.tld/otherfile.zip
This will download the file https://somedomain.tld/otherfile.zip into the /tmp folder and save it under the name otherfile.zip.
Download multiple files at once
You can download multiple files, even from different web protocols like HTTP, HTTPS, and FTP. Use the wget command with URLs. A practical implementation is given below.
$ wget <HTTP URL> <FTP URL>
$ wget https://somedomain.tld/otherfile.zip https://seconddomain.tld/file.zip
Note: you can download any type of file by using the wget command like .txt, .tar, .zip, .png, etc.
Download files in Background
You can immediately download files in the background by using wget -b command. To know about the download file status log will be written in the wget-log file. The output of the command is given below.
$ wget -b <website URL>
$ wget -b https://somedomain.tld/otherfile.zip
This will download the file otherfile.zip into the current directory. the command prompt will return immediately, so you can continue to work on the shell while the download continues in the background.
Restrict limit to download file
You can restrict the download file limit by using –limit-rate=512k. It’s mean that if you don’t want to download more than 512k or limit, then you will use this command with wget. The implementation is given below.
$ wget --limit-rate=512k <download url>
$ wget --limit-rate=512k https://somedomain.tld/files/archive.zip
This command will download the file archive.zip into the current folder, the download rate will get limited to 512Kbit/second.
You can find help related to wget by using –help command.
$ wget --help

Resume interrupted downloads
Sometimes, when we are downloading a file from the internet, at that time error may occur due to internet connection problems. For this purpose, you can resume the download from where the file stops downloading. The following command is used to resume uncompleted downloads.
$ wget -c <website URL>
