Linux looks at the process based on the PID

On Linux, you can view a process based on a PID in one of the following two ways:

1. Use the /proc file system: In Linux, each running process has a corresponding directory in the /proc file system. You can go to the /proc/ directory to view various process information. For example, you can use the command 'cd /proc/12345' to go to that directory and then use the 'ls' command to view the files and subdirectories in that directory that contain various information about the process.

2. Use the command line tool: You can use the command 'tasklist /svc' to view the PID corresponding to the system command. In addition, you can use the Task Manager view to view the PIDs corresponding to system processes. The specific operation is to press the Ctrl-Alt-delete key to bring up the task manager, open the process, click the view---select column---check in the pop-up window in front of the PID, and after confirmation, the process number of the process is below the PID.

It should be noted that the above methods can help users with system monitoring and troubleshooting, but the specific operation may vary slightly depending on different Linux distributions.
