The Heart of Linux: What Language Is It Built In?

Linux, the open-source operating system that powers a vast portion of the digital world, is often celebrated for its versatility and high-performance. But what is the language that forms the backbone of this robust system?

In the realm of Linux, the primary language used for building its core components is C. It's known for its efficiency, close-to-the-hardware capabilities, and robust performance, making it an ideal choice for such a critical task.

Is Linux written in C?

However, the Linux kernel is not solely crafted in C. In more recent developments, there's been an intriguing addition to the mix – Rust. This newer language has gained traction in the Linux community, especially for certain ancillary components.

There's also a touch of assembly in the Linux recipe. While the kernel itself is primarily constructed using C, assembly language plays a crucial role in the low-level parts of the system, enhancing its performance and interaction with hardware.

When it comes to the GNU tools, which are often used in conjunction with Linux, the C language is the go-to choice for development.

It's worth noting that the Linux kernel source code is available for everyone to explore on kernel.org, offering a transparent view of its inner workings. While C remains the cornerstone, the Linux community is not averse to experimentation, and this vibrant ecosystem continues to evolve.
