to verify that wget is now installed on your Ubuntu system.

And that’s another fix for the wget command not found error, in Ubuntu Linux.

Fixing wget issue by updating system’s PATH

If wget is already installed but not accessible, you may need to update your system’s PATH environment variable to include the location of the wget executable.

You can do this by adding the following line to your shell’s configuration file (e.g., ~/.bashrc or ~/.bash_profile):bash

export PATH="/usr/bin:/usr/local/bin:$PATH"

Save the file and then restart your shell or run source ~/.bashrc (or source ~/.bash_profile) to apply the changes.

What causes the wget command not found issue?

The “wget command not found” issue can occur on any Linux system if the wget command-line utility is not installed or not accessible.

There can be a few reasons for this error:

• Package not installed: The wget package might not be installed on the system. This can happen if the system is minimal or if the package was not included during the initial installation.
• PATH environment variable: The wget executable might not be in the system’s PATH environment variable. This means the system doesn’t know where to find the wget command when it’s executed.
• Limited user permissions: The user running the command may not have sufficient permissions to access or execute the wget command.

To fix the “wget command not found” issue, you can follow the steps mentioned in this article to install wget using the appropriate package manager for your Linux distribution.

How to fix in other OS’es?

It’s worth noting that some minimal or specialized Linux distributions may not have wget available in their default package repositories. In such cases, you might need to use alternative methods to download files, such as using curl or manually installing wget from other sources.

Install wget: Use the package manager specific to your operating system to install wget. Here are the commands for some popular package managers:

For Ubuntu/Debian-based systems:

<code>sudo apt-get install wget</code>

For CentOS/Fedora-based systems:

<code>sudo yum install wget</code>

For Homebrew on macOS:

<code>brew install wget</code>

What is the wget command?

The wget command is a popular command-line utility used for retrieving files from the web. It stands for “Web Get” and is commonly available on Unix-like systems, including Linux.

The basic syntax of the wget command is as follows:

wget [options] [URL]

Here, [options] represents various command-line options that modify the behavior of wget, and [URL] is the web address (URL) of the file you want to download.

Some common options and use cases of wget include:

Downloading a file: You can simply provide the URL of the file you want to download, and wget will retrieve it. For example:

wget http://example.com/file.txt

Specifying output filename: By default, wget saves the downloaded file with its original name. You can use the -O option to specify a different output filename. For example:

wget -O output.txt http://example.com/file.txt

Recursive downloading: wget can recursively download files, allowing you to retrieve an entire directory or website. The -r option is used for recursive downloading. For example:

wget -r http://example.com/directory/

Resuming interrupted downloads: If a download is interrupted, wget can resume it from where it left off using the -c option. For example:

<code>wget -c http://example.com/largefile.zip</code>

These are just a few examples of the capabilities of the wget command. wget provides many more options and features, allowing you to customize the download process according to your needs. You can refer to the wget manual or documentation for a comprehensive list of options and their usage.

What are the wget compatible OS where the error wget command not found can occur?

Here are some additional details about the availability and usage of the wget command in different operating systems:

• Linux: wget is widely available and commonly used on various Linux distributions. It is often included by default or can be installed easily using package managers like apt, yum, or dnf. Linux users rely on wget for downloading files from the web, recursive downloads, resuming interrupted downloads, and more.
• macOS: wget is not included as a preinstalled command on macOS. However, macOS users can install it using package managers like Homebrew or MacPorts. Homebrew is a popular choice for macOS users to install and manage command-line utilities, including wget. Once installed, wget functions similarly to its usage on Linux systems.
• Unix-like systems: Apart from Linux and macOS, wget is available and commonly used on various Unix-like systems. This includes FreeBSD, OpenBSD, and Solaris, where users can typically install wget using package managers specific to those operating systems.
• Windows: While wget is primarily associated with Unix-like systems, there are also ports of wget available for Windows. These ports provide the functionality of the wget command-line utility on Windows systems. Examples of Windows ports include GNU Wget for Windows (also known as GnuWin32) and Wget for Windows (native Windows port). Users can download and install these ports to use wget commands within a Windows command prompt or PowerShell.

It’s important to note that the usage and behavior of wget commands are generally consistent across different operating systems once the utility is installed. However, installation methods may vary depending on the specific operating system or package manager used.

How to check if wget command is corrupted?

To check if the wget command is corrupted, you can follow these steps:

Open a terminal on your Linux system. Run the which wget command to determine the location of the wget executable. This command will display the path to the wget binary.

which wget

If the wget command is properly installed and accessible, it will output the path to the wget executable (e.g., /usr/bin/wget).

Once you have the path to the wget executable, you can verify its integrity by running the file command followed by the path to the wget binary.

file /usr/bin/wget 

The file command examines the file type and content. It will provide information about the wget binary, confirming whether it appears to be a valid executable file.

If the output indicates that the file is a dynamically linked executable (ELF), it suggests that the wget command is likely not corrupted. However, if the output indicates an unexpected file type or mentions “broken” or “corrupted,” it may indicate an issue with the wget binary.

If you suspect that the wget command is indeed corrupted, you can try reinstalling it using the appropriate package manager for your Linux distribution. Reinstallation typically resolves issues with corrupted binaries.

Alternative commands, different than wget

There are alternative commands to wget that offer similar functionality for downloading files from the web. An alternative way to fix the wget command not found issue, is using a different tool to download files.

Here are a few popular alternatives:

• curl: curl is a versatile command-line tool available on various operating systems, including Linux, macOS, and Windows. It supports downloading files using various protocols (HTTP, FTP, etc.) and offers extensive features and options. For basic file downloads, you can use curl -O <URL>.
• fetch: fetch is a command-line utility commonly found on BSD-based systems, including FreeBSD and macOS. It is designed specifically for file retrieval and can handle FTP and HTTP protocols. To download a file using fetch, you can use the command fetch <URL>.
• aria2: aria2 is a powerful command-line download manager that supports parallel and segmented downloading. It can download files over HTTP, FTP, BitTorrent, and more. aria2 is available on various operating systems, including Linux, macOS, and Windows. The basic usage is aria2c <URL>.
• wget2: wget2 is an alternative version of wget that aims to provide additional features and improvements over the original wget. It offers enhanced performance, parallel downloading, and improved support for protocols. wget2 is still in development and may not be as widely available as wget or the other alternatives.
• scp: scp command is used to transfer files or directories from a server to another.

These alternative commands provide similar functionality to wget and may offer additional features or improvements in certain cases. The choice of command depends on the specific requirements and preferences of the user and the availability of the tool on the operating system being used.
