You Should Know: Essential Linux Commands & Practices
To complement the eBook, here are key Linux commands and steps every Cloud & DevOps engineer must master:
1. Linux File System Hierarchy
View directory structure
tree /
Check disk usage
df -h
Find large files
find / -type f -size +100M -exec ls -lh {} \;
2. Kernel & System Monitoring
Check kernel version uname -r Monitor system resources top htop Check running processes ps aux | grep <process_name>
3. Networking & Security
Check open ports ss -tulnp Configure firewall (UFW) sudo ufw enable sudo ufw allow 22/tcp Test network connectivity ping google.com traceroute google.com
4. User & Permission Management
Add a new user sudo adduser <username> Grant sudo access sudo usermod -aG sudo <username> Modify file permissions chmod 755 <file> chown user:group <file>
5. Automation with Cron & Systemd
Schedule tasks with cron crontab -e Example: Run a script daily at 2 AM 0 2 /path/to/script.sh Manage services with systemd sudo systemctl start <service> sudo systemctl enable <service>
6. Cloud-Specific Linux Commands
Check cloud instance metadata (AWS) curl http://169.254.169.254/latest/meta-data/ Mount cloud storage (AWS EBS) lsblk sudo mount /dev/xvdf /mnt/data
