cURL is a tool for transferring data using URLs from the command line. It supports protocols such as HTTP, HTTPS, and FTP, making it useful for web development and server management.
On many Linux systems, including Ubuntu, cURL isn't installed by default, except on Ubuntu Server, where it's commonly used for system administration and advanced tasks. Regular desktop users typically don't need cURL pre-installed.
Installing cURL is straightforward as it's available in default software repositories. Ubuntu users can install it using either the snap or apt package management systems, based on their preference.
Steps to install curl on Ubuntu:
- Launch terminal.
- Update apt package list.
$ sudo apt update [sudo] password for user: Hit:1 http://ports.ubuntu.com/ubuntu-ports jammy-security InRelease Hit:2 http://ports.ubuntu.com/ubuntu-ports jammy-proposed InRelease Hit:3 http://us.ports.ubuntu.com/ubuntu-ports jammy InRelease Hit:4 http://us.ports.ubuntu.com/ubuntu-ports jammy-updates InRelease Hit:5 http://us.ports.ubuntu.com/ubuntu-ports jammy-backports InRelease Reading package lists...
