Debian Fcitx installation tutorial

Confirm the target hard disk device name (such as /dev/sda) to avoid accidentally deleting the system disk; 2. Use sudoddif=/dev/zeroof=/dev/sdXbs=1Mstatus=progress to overwrite the zero value in full disk, which is suitable for most scenarios; 3. Use sudoshred-v-n3/dev/sdX for three random data overwrites to ensure that it cannot be restored; 4. Optionally execute sudobadblocks-wsv/dev/sdX for destructive write tests; finally use sudohexdump-C/dev/sdX|head to verify whether it is all zero and complete safe erasing.

If you want to know the Linux system information and version, you can use the following steps: 1. Use lsb_release-a to view the distribution information; 2. View the /etc/os-release file to obtain version details; 3. Use uname-r or uname-mrs to confirm the kernel version and system architecture; 4. Run lscpu, free-h or dmidecode (requires root permissions) to obtain hardware information. The above method is applicable to different distributions, and some commands may require installation or permission adjustment.

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.
