How to limit the resources a process can use with ulimit?
ulimit is a tool in Linux that limits the use of process resources, and supports setting file size, file descriptors, number of processes, memory and CPU time. 1. Common options include -f (file size), -n (file descriptor), -u (number of processes), -v (virtual memory), -t (CPU time), and -l (locked memory). 2. Supports soft limits (-S, currently in effect but cannot exceed hard limits) and hard limits (-H, set by root). 3. The temporary setting fails after restarting. Persistence needs to be written to the script under /etc/security/limits.conf or /etc/profile.d/. The systemd service also needs to add Li to the service file.

How to password protect a file or folder in Linux?
File or folder encryption can be achieved through a variety of tools in Linux. 1. Use zip to encrypt folders: zip-r-P password to package the original folder, and it is safer to enter passwords interactively; 2. Encrypt a single file with gpg: generate an encrypted file with gpg-c file name, and decryption requires gpg-o original file-d to encrypt the file; 3. Encrypt the entire directory: after installation, create an encrypted mount point, and automatically encrypt the write content after setting the password, and the file is unreadable after uninstallation; 4. Other tools such as 7z and VeraCrypt are suitable for packaging encryption and virtual encryption disk scenarios respectively. The right approach can be selected based on security, long-term use and cross-platform needs.

Is Linux more secure than other operating systems?
Linux is generally considered safer than Windows and macOS, but not absolutely immune. Its security advantages stem from design, user habits and usage methods. First, Linux desktop has a small market share and is less attacked, but we still need to be wary of the risk of improper server configuration; second, the default strong permission model limits the operational permissions of ordinary users and reduces the harm of malware; in addition, open source features enable vulnerabilities to be quickly discovered and fixed, but rely on community maintenance quality; finally, system security also depends on user configuration and usage habits, such as updating software, avoiding arbitrary installation of packages and reasonably setting up SSH access. So while Linux is more secure in design, it is still crucial to use it correctly.

What is the Linux filesystem hierarchy?
The Linux file system hierarchy is a standardized directory organization method used to standardize the storage location of files and resources. 1. The root directory (/) is the starting point of the entire system, and all other directories are mounted here; 2./bin stores basic commands for ordinary users, and /sbin stores administrator commands, both are still available in single-user mode; 3./etc saves the configuration files of the system and services, such as /etc/passwd, /etc/hosts, etc.; 4./home is the home directory of ordinary users, and /root is the home directory of super users; 5./dev contains device files, representing hardware devices; 6./proc and /sys provide dynamic information of the kernel, hardware and processes; 7./tmp and /var/

What is the purpose of the /proc filesystem?
The /proc file system is a virtual file system in Linux that is used to view the kernel running status in real time, providing process and system information. It is not stored on disk, but resides in memory, and the content changes dynamically with the process running and system state. Each process has a directory named after its PID under /proc, including cmdline, status, fd and other files, which record the startup command, status summary and open file descriptors respectively, for easy debugging and monitoring. In addition, /proc also provides system-level information, such as /proc/cpuinfo displays CPU details, /proc/meminfo displays memory usage, /proc/version views kernel version, /proc/load

How to check my IP address in Linux?
Use ipaddrhow to view all network card IP information, or ipa abbreviation commands; 2. Use ipaddrhoweth0 to view specific network card information; 3. Use hostname-I to quickly obtain all IPv4 addresses; 4. The graphical interface can be viewed in the network settings. It is recommended to use the IP command first. Hostname can be used in the script, and the graphical interface is suitable for desktop users.

How to copy a file or folder in Linux?
Copying files or folders in Linux is mainly done through the CP command. 1. When copying a single file, use the target path of the cp source file. If you do not want to overwrite the existing files, you can add the -i parameter to ask for confirmation. 2. The -r parameter is required to copy the folder to achieve recursive copying, such as the target path of the cp-r source directory. 3. Keep file attributes available with -p parameters, or use archive mode -a to retain permissions, timestamps and other metadata. 4. Common techniques include adding -v to display the detailed process, completing the file name with the Tab key, copying multiple files to the same directory at once, and using sudo to increase permissions when copying across users. Mastering these parameters can effectively avoid misoperation and data loss.

How would you troubleshoot a server with high CPU usage?
If the server CPU usage rate is too high, first check the processes in top or htop to see if any abnormal processes occupy high resources; secondly, use sar or mpstat to analyze historical trends; then review the application log to check code or query problems; then consider the impact of system level such as number of processes, swap memory, etc.; finally take measures such as restarting services, optimizing code or expanding capacity to solve them. 1. Run top/htop to identify high CPU processes; 2. Use sar/mpstat to analyze time trends; 3. Check log positioning application problems; 4. Troubleshoot system-level problems; 5. Perform repair operations.

Why is Windows 11 desktop background blurry?
Windows 11 desktop blurring is usually caused by three reasons and needs to be solved separately. 1. When the image resolution does not match the screen size, the system will stretch the picture and cause blur. You should use the drawing tool or online adjuster to adjust the wallpaper to the screen native resolution (you can view it in Settings > System > Display). 2. Using low-quality formats such as high-compressed JPEG or social media thumbnails will cause distortion. It is recommended to use PNG format instead or obtain high-definition wallpapers from websites such as Unsplash, and avoid using mobile phone screenshots. 3. Display zoom settings may affect clarity. You can go to Settings > System > Display > Scaling and Layout to try different options, and switch to "Fill" and "Stretch" in Personalization > Background.

How to customize the Linux terminal?
Linux terminals can improve user experience through personalized settings. Specific methods include: 1. Modify the color theme, adjust the PS1 variable in the .bashrc or .zshrc file, or use toolkit such as oh-my-zsh to change the color scheme; 2. Customize the prompt format, you can add information such as the current path, time, Git branch, etc., such as using colors to distinguish username, hostname and path, or display time before the prompt; 3. Install plug-in enhancements, such as automatic completion, syntax highlighting, quick jump directory provided by oh-my-zsh; 4. Set aliases to simplify the input of common commands, such as setting "gitstatus" to "gs", or setting "ls-la" to "ll", or

Why is Windows 11 making my headset sound distorted?
Problems with distortion of headphones in Windows 11 are usually caused by system setup or driver problems rather than hardware failures. 1. You can first check audio enhancements such as "loudness equalization" or "bass enhancement", turning off these features may improve sound quality. 2. Secondly, audio drivers are outdated or damaged, and can be solved by updating, reinstalling or rolling back the driver through Device Manager. 3. If the default audio format is incompatible with the headset, it may also cause distortion. You can adjust the sampling rate and bit depth in the sound settings to match the headset's capabilities. 4. If you use Bluetooth headsets, you can also check the Bluetooth audio codec settings, disable unnecessary encoding formats, and choose a better compatibility such as SBC or AAC. Follow the above steps to check step by step, usually Windo can be solved
