How to monitor system performance in real-time with top or htop?
top and htop are practical command-line tools for real-time monitoring of system performance. They can quickly view CPU, memory usage and running processes, and are suitable for troubleshooting server lags or excessive resource usage. Common operations include: sorting by CPU by P in top, sorting by M by memory, expanding CPU core information by 1, exit by q, and terminate the process by k; htop provides a more intuitive interface, supports mouse operation and color distinction, and can be sorted by F6, send signals by F9, and exit by F10 or q after installation; tips include setting refresh intervals (such as top-d2), filtering specific user processes, avoiding misjudgment of instantaneous peaks, paying attention to zombie processes, etc. Mastering these functions can effectively help position the system bottlenecks, which is a must in a server environment without graphical interfaces.

How to test network connectivity with ping and traceroute?
Use ping and traceroute to troubleshoot network connectivity issues. 1. Use ping to check basic connectivity. If you return "64bytesfrom..." to indicate network access, it may be disconnected if "Requesttimedout" is displayed; 2. Use traceroute to view the routing path. A certain jump is an asterisk, which may be a node failure or a firewall blocking; 3. First, the public network IP is tested and then the domain name is tested to determine whether the DNS is normal; 4. Combine the two to analyze the overall connectivity and specific failure points; 5. Note that it is normal for some nodes to not respond to ICMP, and it is necessary to try several times to avoid misjudgment.

How to pass arguments to a bash script?
Passing parameters in a Bash script can be achieved by directly entering parameters after the script name. These parameters are accessed in the script through position variables such as $1 and $2. For example, when running ./greet.shAlice, $1 means Alice. If you need to process multiple parameters, you can use a loop to traverse all parameters with "$@". In addition, the getopts function can parse parameters with options (such as -n or -a) to improve script flexibility and ease of use.

What is a PPA and how do I add one to Ubuntu?
PPA is an important tool for Ubuntu users to expand their software sources. 1. When searching for PPA, you should visit Launchpad.net, confirm the official PPA in the project official website or document, and read the description and user comments to ensure its security and maintenance status; 2. Add PPA to use the terminal command sudoadd-apt-repositoryppa:/, and then run sudoaptupdate to update the package list; 3. Manage PPAs to view the added list through the grep command, use the --remove parameter to remove or manually delete the .list file to avoid problems caused by incompatibility or stopping updates; 4. Use PPA to weigh the necessity and prioritize the situations that the official does not provide or require a new version of the software.

How to find a file by its name using find or locate?
Two ways to find files in Linux are to use the find and locate commands. 1. The find command is suitable for real-time search, and the syntax is find[path]-name "file name", which supports wildcard characters, ignoring case (-name), excluding directories (-not-path), and qualified types (-typef). 2. The locate command depends on the database faster, and the syntax is locate-b "* file name", but you need to run updatedb first to update the database. The choice of both depends on whether real-time and speed requirements are required.

How to install Linux alongside Windows (dual boot)?
