What is CLI tools ?
A command line interface (CLI) is a text-based user interface (UI) used to run programs, manage computer files, and interact with a computer. A command line interface is also known as a command line user interface, console user interface, or character user interface.
Why do we use CLI tools ?
The CLI is a command line utility that accepts text input and executes operating system functions. In the 1960s, this was the only way to interact with a computer, as only computer terminals were in use. In the 1970s and 1980s, command line input was widely used on Unix systems and personal computer systems such as MS-DOS and Apple DOS.

Answer:
Thunderbird
Explanation:
When we talk about open source software, we are talking about software that is free to download and its source code repository is made available and public to its users. Open source code can be modified and distributed with the users’ rights if they want to. Thunderbird is an example of open source developed by the Mozilla foundation. All known web browsers like Chromium and Safari are open source apart from Internet Explorer. Internet Explorer has remained closed source for a long time now.
