What to do if modifying the hosts file in Linux does not work

There are three main ways to install software on Linux: 1. Use a package manager, such as apt, dnf or pacman, and then execute the install command after updating the source, such as sudoaptininstallcurl; 2. For .deb or .rpm files, use dpkg or rpm commands to install, and repair dependencies when needed; 3. Use snap or flatpak to install applications across platforms, such as sudosnapinstall software name, which is suitable for users who are pursuing version updates. It is recommended to use the system's own package manager for better compatibility and performance.

Linux is suitable for old hardware, has high security and is customizable, but has weak software compatibility; Windows software is rich and easy to use, but has high resource utilization. 1. In terms of performance, Linux is lightweight and efficient, suitable for old devices; Windows has high hardware requirements. 2. In terms of software, Windows has wider compatibility, especially professional tools and games; Linux needs to use tools to run some software. 3. In terms of security, Linux permission management is stricter and updates are convenient; although Windows is protected, it is still vulnerable to attacks. 4. In terms of difficulty of use, the Linux learning curve is steep; Windows operation is intuitive. Choose according to requirements: choose Linux with performance and security, and choose Windows with compatibility and ease of use.

To manage the startup of Linux services, use the systemctl command. 1. Check the service status: systemctlstatus can check whether the service is running, enabled or disabled. 2. Enable the service startup: sudosystemctlenable, such as sudosystemctlenablenginx. If it is started at the same time, use sudosystemctlenable--nownginx. 3. Disable the service startup: sudosystemctldisable, such as sudosystemctldisablecups. If it is stopped at the same time, use sudosystemctldisabl
