How can you view all running processes on a Linux system?

On Linux, several commands can be used to view all running processes:

• ps aux — displays a list of all processes with detailed information.

• top — an interactive process monitor that updates in real time.

• htop — an improved version of top with a user-friendly interface (if installed).

• pgrep — searches for processes by name.

Example command to display all processes:

ps aux

The output contains information about the user, PID, CPU and memory usage, start time, and process command.

For more detailed analysis, pstree can be used to display processes in a tree structure.
