{"id":4,"count":1,"description":"The Linux operating system is used for many different purposes, from web servers to desktop computers. Its popularity has been increasing in recent years because it is free and open source. This allows users to customize the system to their needs, which is very useful.\r\n\r\nIn this article, we will look at some nuances of working with the Linux operating system, which may be useful for beginners.\r\n<h2>Installing packages.<\/h2>\r\nLinux has a large number of packages that can be installed using various tools such as dpkg, apt-get, yum, etc. These tools make it easy to install, update, and remove packages. For example, to install a package, you can use the command:\r\n<blockquote><strong><code>sudo apt-get install package_name<\/code><\/strong><\/blockquote>\r\nwhere <strong><code>package_name<\/code><\/strong> is the name of the package to be installed.\r\n<h2>Working with standard I\/O streams.<\/h2>\r\nStandard I\/O streams are an important part of working with this operating system. These threads allow you to interact with the command line and perform various actions. In particular, there are three standard streams:\r\n<ul>\r\n \t<li><strong><code>stdin<\/code><\/strong> (standard input stream) that receives data from the user.<\/li>\r\n \t<li><strong><code>stdout<\/code><\/strong> (standard output stream), which outputs the results of the program to the screen.<\/li>\r\n \t<li><strong><code>stderr<\/code><\/strong> (standard error stream), which outputs error messages that occur during program execution.<\/li>\r\n<\/ul>\r\n<h2>Working with the file system.<\/h2>\r\nThe Linux file system is hierarchical, so users can work with files and folders in different directories. In addition, there are many useful commands for working with the file system in Linux, for example:\r\n<ul>\r\n \t<li><code><strong>cd<\/strong><\/code> - change the current working directory.<\/li>\r\n \t<li><strong><code>ls<\/code><\/strong> - list files and folders in the current directory.<\/li>\r\n \t<li><strong><code>mkdir<\/code><\/strong> - create a new directory.<\/li>\r\n \t<li><strong><code>rm<\/code><\/strong> - delete a file or directory.<\/li>\r\n<\/ul>\r\n<h2>Access rights<\/h2>\r\nWorking with access rights in unix-like systems there is a system of access rights to files and directories. This means you can control who has access to your files and directories and how they can interact with them. Each file or directory has its own access rights that determine who can read, write, or execute the file. You can use the <code><strong>chmod<\/strong><\/code> command to change access rights.\r\n<h2>Work with processes.<\/h2>\r\nProcesses in Linux are programs that are running on a computer and run in the background or in another terminal. You can view and manage processes using various commands like <strong><code>ps<\/code><\/strong>, <strong><code>top<\/code><\/strong>, <strong><code>kill<\/code><\/strong>, etc.\r\n<h2>Network<\/h2>\r\nNetworking Linux is a powerful operating system for networking. Linux has many tools for working with the network, for example, <strong><code>ifconfig<\/code><\/strong> - for configuring network interfaces, <strong><code>ping<\/code><\/strong> - for checking connections with other computers, <strong><code>netstat<\/code><\/strong> - for viewing network connections, etc.\r\n<h2>Text Editor<\/h2>\r\nWorking with a text editor There are many different text editors such as vi, nano, emacs, etc. These editors are used to edit text files, configuration files, and scripts.\r\n\r\nLinux is a powerful operating system with many useful tools and features. It is becoming increasingly popular among professional users, programmers and system administrators. Although Linux may seem difficult for beginners, it has many advantages, such as security, stability, and the ability to customize to your needs.\r\n\r\nIf you are going to work with Linux, then it is useful to check the list of the most popular Linux distributions, such as Ubuntu, Debian, CentOS, Fedora, etc. Each of these distributions has its own characteristics, but they are all based on the Linux kernel and share a similar set of tools.\r\n\r\nLearning how to work with Linux can take some time, but it's worth the effort. Linux can be very useful for professional programmers, system administrators, and anyone who works with large amounts of data or needs powerful computing capabilities. Do not be afraid to experiment and explore the possibilities of this powerful operating system, and you will discover many new things for yourself.\r\n<h2>How we use Linux operating systems<\/h2>\r\nWe at the <a href=\"https:\/\/selector.space\" target=\"_blank\" rel=\"noopener\">company<\/a> actively use unix-like operating systems for both server systems and workstations. For example, all web servers are running on Ubuntu Server OS. Various CRMs can also be conveniently and flexibly deployed for stable operation and administration on facilities without a graphical interface with secure access (for example, CentOS).","link":"https:\/\/blog.selector.space\/en\/category\/crm-erp\/","name":"CRM, ERP","slug":"crm-erp","taxonomy":"category","parent":0,"meta":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
