How to check the status of Linux processes?

You can use the following command in Linux to check the status of processes:

1. The ps command is used to list the processes in the current system. Different options can be combined to display various process information, such as using ps aux or ps -ef for detailed information on all processes.
2. The top command allows you to view the current status of processes in real time. By default, it sorts processes by CPU usage and displays detailed information about each process.
3. The htop command provides more interactive features and a graphical interface compared to top, making it easier to view process information.
4. The /proc directory in Linux system contains many files and directories related to processes, allowing users to obtain information about the status of processes by checking these files. For example, the file /proc/PID/status can be used to view the status of a specific process ID.
5. The pstree command displays the relationship between processes in a tree-like structure, showing parent processes, child processes, and so on.

Here are some common commands and methods that you can choose from to view the status of processes as needed.
