How can you obtain information about the current process load in Linux OS?

In Linux, there are several ways to obtain information about the current process load:

1. The top or htop command — interactive utilities that show CPU load, memory, and other process parameters.

2. The ps command — allows you to get static information about processes. For example:

ps -p <PID> -o %cpu,%mem,cmd

3. Reading from /proc — the /proc filesystem contains information about processes and the system. For a specific process, you can look at the /proc/<PID>/stat or /proc/<PID>/status files.

4. Using the pidstat utility — shows resource usage statistics for processes.

Example of using ps for a process with PID 1234:

ps -p 1234 -o %cpu,%mem,cmd

This will display the CPU and memory usage percentages and the command of the process.

For programmatic access, you can read files in /proc or use libraries like psutil in Python.
