Why does every senior DevOps engineer tell you: Learn Linux first?
Before Kubernetes, before AWS, before Terraform… learn Linux. Here’s why 👇
Because no matter how shiny the cloud console looks, every outage eventually drags you down to the command line.
1. Kubernetes Pod failing? → You’ll debug with kubectl exec and land in Linux.2. Pipeline broken? → File permissions, symlinks, or shell quirks.
3. High CPU alert? → top, iostat, vmstat — Linux tools, not AWS dashboards.
The reality: AWS UI can help you start. Python scripts can make you look smart.
But only Linux will save you when prod is burning.
If you’re starting DevOps, learn these first:
1. grep, awk, sed → text wrangling
2. ps, lsof, strace → process forensics
3. netstat, ss, tcpdump → network truth serum
4. systemctl, journalctl → service lifelines
Everything else in DevOps - Kubernetes, Terraform, CI/CD - is built on top of Linux.
Skip this step, and you’ll always feel like an imposter.
If you want to be taken seriously as a DevOps engineer, Learn Linux first. Everything else comes later.
