Most DevOps engineers skip these Linux commands until production breaks at midnight.
Here are the commands that saved me countless hours of panic.
Master the basics first. Get comfortable with ls, cd, pwd, mkdir, and rm.
Use grep to search logs when things break. Learn find to locate files fast.
Combine commands with pipes. ps aux | grep nginx shows exactly what is running.
Use systemctl to manage services. systemctl status checks health. systemctl restart fixes most issues.
Learn tail for live logs. tail -f /var/log/syslog watches errors in real time.
SSH keeps you connected. ssh-keygen and ssh-copy-id eliminate password fatigue.
Disk space kills servers. df -h shows available space. du -sh checks folder sizes.
Process management saves uptime. top and htop reveal CPU hogs. kill and killall stop runaway processes.
Permissions matter. chmod 600 protects private keys. chmod +x makes scripts executable.
Backups prevent disasters. tar czf backup.tar.gz /data compresses and saves. rsync syncs files efficiently.
The command line is not optional. It is your foundation for containers, Kubernetes, and cloud work.
