Key Linux Components

Component	Description	Function
Kernel	Core of Linux OS	Manages hardware resources
Shell	Command-line interface	Interprets user commands
File System	Data storage structure	Organizes and manages files

Basic Linux Command Examples

Here's a practical demonstration of fundamental Linux commands:

## System information
uname -a

## List directory contents
ls -la /home

## Check current user
whoami

## Display system resources
free -h
df -h

These commands showcase essential Linux operations, providing insights into system configuration, file management, and resource monitoring.

Linux Process Management

Linux manages processes through sophisticated mechanisms, allowing efficient execution and resource allocation. Process management involves creating, scheduling, and terminating system tasks.

Process Control Example

## List running processes
ps aux

## Start background process
./script.sh &

## Kill a specific process
kill -9 [PID]

The demonstrated commands illustrate basic process control techniques in Linux environments.
