To get all process information in Linux, you can use various commands and tools. Here are a few methods:

  1. ps Command: The ps (process status) command provides information about currently running processes. The basic command ps can be used to display a snapshot of active processes. Additional options can be used to customize the output, such as ps aux for a more detailed list.
  2. top Command: The top command provides a real-time, dynamic view of processes. It displays the CPU usage, memory usage, and other details for each running process. Simply execute the top command in the terminal to launch the process viewer.
  3. System Monitor: Most Linux distributions provide a system monitoring application, such as GNOME System Monitor or KDE System Guard. These graphical tools provide detailed information about system processes, including CPU and memory usage, network activity, and more.
  4. htop Command: htop is an interactive process viewer that provides an alternative to the top command. It presents all running processes in a more user-friendly, customizable manner. To install htop, use the package manager for your Linux distribution (e.g., sudo apt install htop on Ubuntu), and then launch it by executing htop in the terminal.
  5. /proc Filesystem: The /proc filesystem in Linux provides access to information about processes. By navigating to the /proc directory, you can find detailed information about each running process. For example, accessing /proc/[PID] displays information about a specific process, where [PID] is the process ID.

Choose the method that suits your needs and preferences to obtain process information in Linux.
