So, for example, you can put wget in a script to download a web page that gets updated with new data frequently, which is something a browser can't really be used for. Wget is primarily used when you want a quick, cheap, scriptable/command-line way of downloading files. If you are concerned about privacy, there's a million ways to clean a browser up (or you could use a less featureful browser, like Lynx if you really wanna get barebones without destroying all semblance of human user interface). There's literally no upside to using wget as a human. Browsers render HTML, make links clickable (as opposed to having to copy the URL into another wget command manually), etc. Check the related man pages for a complete list of options available for both curl and wget.Typically you would never use it "instead of a browser". This post only touches some of the most common features of what these commands can do. The curl and wget commands can be very useful when added to scripts to automatically download RPM packages or other files. If a type is not specified, it will default to dot. ![]() With wget, you can supply a type (dot or bar) to determine the ASCII visual of the progress bar. To save a file with a new name when using wget, utilize the -output-document option, or more simply -O. The syntax differs, however, if the option and nameserver addresses are joined with an =. You can specify one or more specific DNS servers to use when utilizing wget to access a remote server. Like curl, you can supply various options to your wget command syntax: wget Here is an example of the basic wget syntax: $ wget By default, the information received is saved with the same name as in the provided URL. Unlike curl, the wget command is solely for the retrieval of information from a remote server. The -verbose option with curl is useful for debugging and displaying what is going on during the call to the URL. Note: sslv2 and sslv3 are considered legacy by the maintainer though still available. ssl specifies SSL needs to be used and -sslv3 specifies SSL version 3. Like with HTTP, you can specifically tell curl to use a specific SSL option for the command to connect to and in this case we are specifying version 2. This option displays the progress of the file transfer when combined with the -output option. ![]() If you need to retrieve a file from a remote server via a URL, -output is an easy way to save the file locally. http2 and -http1.1 function in the same way and can be used to verify a webserver. You can specifically tell curl to use the http3 protocol to connect to the host and port provided with a https URL. This list can be handy when troubleshooting DNS issues or if you need to resolve an address against a specific nameserver. This option allows you to list DNS servers curl should use instead of the system default. This option is handy to prevent the connection from terminating too quickly, and to minimize the amount of time you want the command to attempt the connection. The -connect-timeout option sets the maximum time in seconds that curl can use to make its connection to the remote server. When uploading a file, this option allows you to append to the target file instead of overwriting it (FTP, SFTP). The following are some of the available options used with curl and examples of their use. It is the options which make curl so robust. You can supply various options to your command syntax: curl ![]() The syntax for curl is fairly straight-forward at first glance. Administrators commonly rely on curl to interact with APIs using the DELETE, GET, POST, and PUT methods, as explained here. In addition to HTTP, you can use other protocols, including HTTPS, FTP, POP3, SMTP, and Telnet. You could use either of them to automate downloads from various servers.Īs mentioned, the curl command allows you to transfer data from a network server, but it also enables you to move data to a network server. ![]() Both commands allow you to transfer data from a network server, with curl being the more robust of the two. The *nix commands curl and wget are useful for accessing URLs without resorting to a browser.
