Is Linux more secure than Windows?
Linux is not inherently more secure than Windows, its security depends on how it is used and managed. 1. Both have built-in security features, such as SELinux for Linux, AppArmor for Windows, Defender for Windows, and BitLocker for Windows, but security depends on configuration and updates; 2. Windows has become the main target of attack due to large user base. Although Linux is less threatened, it may still be hacked due to improper configuration; 3. User behavior and system management are crucial. Whether running programs as an administrator or installing unofficial software will increase risks, while Linux users usually have better security habits; 4. In enterprises, Linux is suitable for automated security policies.

What is the difference between [ ] and [[ ]] for conditional tests?
In Bash scripts, [] is synonymous with the test command, suitable for portability across shells; [[]] is the Bash keyword, providing more powerful and secure features. 1.[] variables need to be strictly referenced to avoid errors, while [[]] is more tolerant to unreferenced variables; 2.[[]] supports regular expression matching (=~) and wildcard pattern matching (==), while [] does not support it; 3.[[]] allows the use of && and || combination conditions without additional brackets; 4. If cross-platform compatibility is required, [] should be used. If it is for Bash, it is recommended to use [[]] for clearer syntax and advanced features.

How to exit Vim in Linux
To exit Vim, you must first press the Esc key to enter command mode, then enter: q and press Enter to exit. If the file has been modified and wants to save and exit, use:wq to enter; if you do not want to save and force exit, use:q! to enter. Reasons for not being able to exit may include not entering command mode correctly, files being locked or read-only, spelling errors, and files being occupied by other programs. The solutions are to ensure that Esc is pressed to enter command mode, use q! to exit and abandon changes, check the spelling of the command, and close the program that occupies the file. Additionally, you can use nano instead of Vim or configure the default editor to nano to simplify operations. Mastering these basic steps is one of the keys to Linux operations.

How to dual boot Linux and Windows
The key to installing a dual system is partitioning and boot settings. Just pay attention to the following points to run stably: ① Back up data before partitioning, use Windows disk management or third-party tools to make unallocated space available. Linux is recommended to separate /, /home and swap separately; ② The installation order must be Windows after Linux, otherwise the boot needs to be repaired manually; ③ Make sure that the boot mode of UEFI or Legacy is consistent, and select the right boot position during installation such as /dev/sda; ④ The boot menu can be adjusted through grub-customizer or editing grub files, and enter Linux after a few seconds by default. Be sure to carefully confirm each step during operation to avoid problems caused by misoperation.
