Linux operating system package introduction

Linux is a free and open source operating system whose kernel was first released by Linus Torvalds in 1991. The Linux operating system consists of many different software packages that provide various features and tools that enable the operating system to run and perform various tasks. In this article, we will introduce some common Linux operating system packages, along with their functions and uses.

  1. apt-get

apt-get is a command line tool for package management in Debian and Debian-based Linux distributions such as Ubuntu. It helps users install, update, and uninstall software packages, as well as resolve package dependencies. Here are some examples of common apt-get commands:

  • Install packages: sudo apt-get install package_name
  • Update package list: sudo apt-get update
  • Upgrade installed packages: sudo apt-get upgrade
  1. yum

yum is a package management tool in distributions such as Red Hat Enterprise Linux (RHEL) and CentOS. It can automatically resolve package dependencies and install and update software by downloading packages from software sources. The following are examples of some commonly used yum commands:

  • Install the package: sudo yum install package_name
  • Update the package: sudo yum update
  • Search for software packages: yum search keyword
  1. systemd

systemd is used to start the Linux system , System and Service Manager that manages and monitors system services. It replaces the traditional init system and provides faster startup speed and more powerful functions. Here are some examples of common systemd commands:

  • Start the service: sudo systemctl start service_name
  • Stop the service: sudo systemctl stop service_name
  • Restart the service: sudo systemctl restart service_name
  1. gcc

gcc is one of the GNU compiler collections Component, is an open source compiler for compiling C, C and other programming languages. It can compile source code into executable files and supports many different compilation options. The following is an example of using gcc to compile a C program:

#include <stdio.h>

int main() {
    printf("Hello, World!
");
    return 0;
}

Use the following command to save the above code as hello.c and compile it into an executable file hello via gcc:

gcc -o hello hello.c
  1. openssl

openssl is an open source encryption toolkit for providing Secure Socket Layer (SSL) and Transport Layer Security (TLS) protocols. implementation, as well as the functionality to encrypt and decrypt data. Here is an example of using openssl to generate an RSA key pair:

openssl genrsa -out private.key 2048
openssl rsa -pubout -in private.key -out public.key

The above is an introduction to some common Linux operating system packages, their functions and usage. The Linux operating system has rich software package resources. Users can choose appropriate software packages according to their own needs and combine them with command line tools to implement various tasks and operations. I hope that through the introduction of this article, readers will have a deeper understanding of the software packages of the Linux operating system.
