What is the difference in purpose between ps and top when viewing processes and resource consumption?

The ps and top commands are used to view processes and resource consumption, but serve different purposes:

• ps is a static snapshot of current processes at the moment of invocation. It displays a list of processes with their parameters (PID, status, runtime, etc.) and does not update automatically. It is used for one-time analysis.

• top is an interactive tool that updates information about processes and their resource usage (CPU, memory) in real time. It allows observing dynamics, sorting processes, and terminating them.

Example usage:

ps aux | grep myprocess  # view processes named myprocess

top                     # start real-time process monitoring
