Linux – Explained In 200 Words

Linux is a Unix-like, open-source operating system kernel first released by Linus Torvalds in 1991. It forms the core of various Linux distributions, such as Ubuntu, Debian, Fedora, and CentOS, which package the Linux kernel with additional software and utilities to create complete operating systems.

Linux is known for its stability, security, and flexibility, making it a popular choice for servers, embedded systems, and even desktop computers. Unlike proprietary operating systems like Windows and macOS, Linux is distributed under open-source licenses, allowing users to view, modify, and distribute its source code freely.

One of Linux’s defining features is its strong support for multitasking and multi-user environments, enabling efficient resource management and concurrent execution of processes. It also boasts a robust set of command-line utilities and a powerful shell (such as Bash) for scripting and automation.

Linux is highly customizable, with users having the freedom to choose their preferred desktop environment, package manager, and software stack. Its modular design and extensive community support make it suitable for a wide range of applications, from web servers and databases to embedded devices and smartphones.

For example, here’s a simple command-line script in Linux to list all files in the current directory:


ls


In this script, the `ls` command is used to list files and directories in the current directory. Running this command in a Linux terminal will display a list of files and directories present in the current location.
