How can active processes in the system be identified?

Active processes in the system can be identified in various ways depending on the operating system:

• Linux/Unix:

  • The command ps aux — displays a list of all processes with detailed information.
  • The command top or htop — interactive view of active processes and their resources.
  • Using pidof to find the PID of a specific process.

• Windows:

  • Task Manager — a graphical interface for viewing processes.
  • The command tasklist in the command prompt — displays a list of processes.

• Programmatically:

  • In scripts, system commands or APIs can be used to obtain a list of processes.

Example command in Linux:

ps aux | grep process_name

This allows you to see all active processes, filtering by name.
