Due to the need to operate and maintain the server, we will use some Linux Shell commands to perform operations and view the detailed information of the server. Here are 10 common Linux commands and functions for viewing process details.
1. ps: used to display snapshots of currently running processes. Common options include:

ps aux: displays all processes for all users.

ps -ef: Display complete information of all processes.

2. top: Displays the processes and resource usage running in the system in real time. Press the q key to exit.

3. htop: Similar to the top command, but provides more interactive functions and information display.

4. pgrep: Find and display the process ID based on the process name or other conditions.

5. pidof: Find and display the process ID based on the process name.

6. pstree: Display processes and their relationships in a tree structure.

7. lsof: Displays a list of processes that have open files.

8. netstat: View process information related to network connections.

9. ss: Another command used to view socket information and network connection status.

10. /proc/<PID> directory: The Linux system maps each running process to the corresponding subdirectory under the /proc directory, where <PID> is the ID of the process. Various information about the process can be viewed in this directory, such as:

/proc/<PID>/status: Process status information.

/proc/<PID>/cmdline: command line parameters.

/proc/<PID>/limits: Resource limits of the user to which the process belongs.

/proc/<PID>/fd/: List of file descriptors opened by the process.

These commands and directories provide multiple ways to view detailed information about the process. You can choose the appropriate command to view process-related information according to your needs.
