Running Linux from the command line involves executing various commands and interacting with the Linux operating system without relying on a graphical user interface (GUI). The command line in Linux is often accessed through a terminal emulator or a virtual console. Here are the basic steps to run Linux from the command line: Access the Command Line Interface (CLI) Open a terminal emulator: On most Linux distributions, you can find a terminal emulator in the application menu or by using a keyboard shortcut (e.g., Ctrl+Alt+T). Access a virtual console: You can switch to a virtual console by using keyboard shortcuts like Ctrl+Alt+F1 to Ctrl+Alt+F6. Each virtual console is a separate command line interface, and you can switch between them. Log In If you are using a virtual console or connecting remotely over SSH, you may need to log in with a username and password. If you are using a terminal emulator, you are likely already logged in with your user account. Execute Commands Once you’re logged in, you can start running commands in the terminal. Simply type a command and press Enter to execute it. Common Linux commands include ls (list files), cd (change directory), pwd (print working directory), mkdir (create a directory), and touch (create a file), among others. Here’s an example of how to navigate the file system and run basic commands from the Linux command line: bashCopy code $ pwd # Print the current working directory $ ls # List the files and directories in the current directory $ cd ~/Desktop # Change to the “Desktop” directory $ mkdir myfolder # Create a new directory named “myfolder” $ cd myfolder # Change into the “myfolder” directory $ touch myfile.txt # Create a new file named “myfile.txt” $ ls # List the contents of the “myfolder” directory $ cat myfile.txt # View the contents of the “myfile.txt” file $ exit # Log out and close the terminal emulator These are basic commands for file and directory management. Linux training in Chandigarh sector 34 It offers a wide range of commands for various tasks, from system administration to programming, so you can perform a wide variety of tasks from the command line. It’s important to learn and practice these commands to become proficient in using Linux from the command line. What is Linux programming? Linux programming refers to the process of creating software applications and scripts for the Linux operating system. It is a popular open-source operating system that is widely use in various domains, including server environments, embedded systems, desktop computing, and mobile devices. Linux programming involves writing code that runs on Linux and takes advantage of its features and capabilities. Here are key aspects of Linux programming: Linux Kernel Programming This involves working on the core of the Linux operating system, the kernel. Kernel programmers write code that manages system resources, handles hardware interactions, and provides essential services to other software components. Kernel programming often requires a deep understanding of operating system internals, system calls, and device drivers. Application Development Linux is home to a vast ecosystem of software applications, both open source and proprietary. Application developers create a wide range of software, from command-line utilities to graphical user interface (GUI) applications. They often use programming languages like C, C++, Python, and others to build software that can run on Linux. Scripting: Linux is know for its powerful command-line interface, and many tasks can be automated through scripting. Scripting languages like Bash, Python, and Perl are commonly use to create scripts that automate system administration tasks, data processing, and more. Server-Side Development: Linux is a dominant force in the server world. Server-side programming on Linux involves creating web applications, databases, and other server services. Web technologies like PHP, Node.js, and Python with frameworks like Django and Flask are popular choices for server-side development. System Administration and Shell Scripting System administrators use Linux programming skills to automate system management tasks. Shell scripting, in particular, is essential for creating custom scripts to manage and monitor Linux servers and services. Embedded Systems Linux course in Chandigarh sector 34 It is commonly use in embed systems, such as IoT devices and consumer electronics. Embedded systems programming write software for resource-constrained devices, often using C or C++ and custom-built Linux distributions. Kernel Module Development Kernel module developers create loadable kernel modules that can add to the Linux kernel to extend its functionality or support new hardware. These modules interact closely with the kernel and require in-depth knowledge of kernel programming. Network Programming Linux is widely use in networking, so network programming on Linux involves creating networked applications, protocols, and services. Networking libraries like sockets and frameworks like libpcap are commonly used. Linux programming is versatile and offers a wide array of opportunities for developers and system administrators. The open-source nature of Linux makes it a valuable platform for learning and contributing to the open-source community, as well as building powerful and customized solutions for various purposes.
