How to check zombie process?: To check for zombie processes in a Unix-like operating system, you can use the following steps:

  1. Open the terminal: Launch the terminal application on your Unix-like system. This can usually be found in the “Utilities” or “System” folder of your operating system.
  2. Run the “ps” command: In the terminal, enter the following command and press Enter:
  • perl
  • Copy code
  • ps aux | grep ‘Z’

This command lists all running processes and filters them to show only the ones with a “Z” in the status field, indicating zombie processes.

Check the output: The terminal will display a list of processes with “Z” in the status field, indicating zombie processes. The output will include information such as the process ID (PID), parent process ID (PPID), and other details about the process.

Identify and handle zombie processes: Take note of the process IDs (PIDs) of the zombie processes. Usually, the next step would be to investigate the parent process and understand why it has not properly handled the termination of its child process. The parent process should ideally be responsible for cleaning up the resources of the terminated child process.

Handle the parent process: If you identify a parent process that is not properly handling its child processes, you may need to troubleshoot or fix the underlying issue. This could involve modifying the code of the parent process or terminating and restarting the parent process.

By following these steps, you can check for zombie processes and take appropriate actions to handle them.
