In this tutorial, we will look at curl and wget, how to get started, and most importantly, the differences between them. While axel and aria2 may not be well known, most terminal users know curl and wget. ![]() However, on a terminal, we need to use tools developed for the terminal.When downloading files from the terminal, four tools often come up: curl, axel, wget, and aria2. On a graphical desktop, we can use a GUI browser and click the download button. If there is a key difference between curl and wget that you think is worth mentioning feel free to leave a comment.We often need to download files from remote servers to our local machine.

Default Features – Most default features in wget like redirect-following and cookies are automatically enabled but with curl, most features need to be explicitly enabled.Parallel Transfers – Curl is capable of achieving multiple parallel transfers which is not the case with wget.On the other hand, curl makes it possible to upload and send data like email through the command-line environment. Upload and Download Capabilities – With wget, you can comfortably achieve plain HTTP POST support.This list includes exotic platforms like TPF and OS/400. Portability – Curl’s dynamic builds enable it to run on more platforms than wget.Therefore, curl is more like the traditional Unix cat command in terms of its implementation while wget mimics the implementation of the Unix cp command. Pipes – With curl, everything is a pipe as stdout receives more stuff and stdin provides the output to be read.Recursiveness – In comparison to curl, wget is stronger when dealing with recursive downloads as you only need to refer it to the remote source/URL containing the targeted file.As for curl, the cross-platform libcurl library powers it. Library – Wget is not associated with any library as it is purely a terminal-based tool.Wget supported protocols are: HTTP, HTTPS, and FTP.Curl-supported protocols are: HTTP, HTTPS, FTP, FTPS, FILE, DICT, TFTP, TELNET, SCP, SMPT, SMTPS, GOPHER, GOPHERS, LDAP, LDAPS, IMAP, IMAPS, RTMP, RTMPS, POP3, POP3S, RTSP, SFTP, SMB, SMBS, or MQTT.Protocols – More protocols are supported by curl than by wget.Now that we know the commonalities of these two commands, it’s time to look at their differences. HTTP cookies are supported by both tools. ![]() HTTP POST requests can be sent via both curl and wget.They are both portable and not limited to a single operating system distribution.They are both free and open-source software.Their default functionality does not need user interaction.Both tools can only be used in the Linux command-line environment to transfer files based on FTP and HTTP(S) protocols.Curl vs Wget Functional Similaritiesīefore we jump into their differences, let’s first look at what unites curl and wget file transfer tools. This article will do its best to address this issue to your satisfaction. However, you as a user need more data in the case of curl versus wget before you can comfortably settle for either of these tools. The above statements check the comparison box of curl vs wget in terms of their definitions. curl is defined as a URL tool used in the transfer of files from/to an active/running server.wget is defined as a non-interactive network downloader of web-based files.However, as per the Linux manual page (man page): ![]() At first glance, you are right to think that both curl and wget are Linux-based utilities used to transfer files over a network via the Linux command-line environment.
