Choose the Best: Wget Vs Curl in 7 Direct Aspects

Wget Vs Curl

Wget vs curl has been a classic debate among many users for a long period now. Both of the utility programs are widely used throughout the world. Both of them can be used for common or intersecting tasks. This is why users often get confused on which one to use for a particular job. There are a lot of similarities between the given two programs, but there are notable differences also. Today, we show you the perfect use case for both of the programs and try to differentiate between them so you can choose which one to use as per your requirements.

What is curl?

The official name of curl is cURL which is short for client Uniform Resource Locator. It is a command-line utility program used to exchange data between a client and a remote host server over multiple protocols. Technically, cURL is a whole software project that provides two main products. A command-line tool called curl and an expandable library called curllib. The project is entirely free and open-source and is also cross-platform. Curl comes pre-installed on Linux and windows. The default output of the curl command is the standard output, and the content is not saved in a file until specified in the command.

What is wget?

Wget is also another utility program that retrieves data from the web. Instead of outputting the data on the standard output by default, it saves the data in a file for permanent usage. Wget is more intended towards downloading the data from the web rather than just retrieving or interacting with the remote host. wget is also easier to use compared to curl if downloading is the primary user concern. wget also has a recursive downloading feature, which is essential when downloading directories of data from the web.

Wget vs Curl: syntax

Both wget and curl share somewhat similar syntax. You provide the program command then options(if any), and then you provide the URL of the data or server you wish to download from. One important thing to note here is that in wget, you don’t need to provide the protocol with the URL, while in curl, the protocol should be prefixed with the URL. The following boxes show the syntax for both utilities for downloading an exe file and saving it on the drive over FTP.

Wget syntax

There is no need to specify the output file in the wget command. It does it automatically; however, it can be done manually if needed.

$ wget www.example.com/fileno1.exe

curl syntax

In curl, you must mention the output file specified with the -o (output) with the same extension to save and use later. Also, remember to use the protocol prefixed with the URL.

$ curl -o fileno1.exe FTP://www.example.com/fileno1.exe

Wget vs Curl for downloading tar file

Tar files are compressed archived files primarily used in the Linux environment. Both of the commands can be used to download a tar file. But if downloading through curl, you would need to specify the protocol and the name and extension of the output saved file, which, if not done correctly, could cause unwanted errors. Therefore to download the tar file, it is better to use the wget command as it doesn’t require any special option to download and save the file. Provide the URL of the tar file with the wget command, and it should be downloaded easily.
