Linux Survival Path
Build command-line confidence from permissions and process triage through incident-grade log forensics.
Path reward
Kernel Monk
Developers, SRE beginners, students, and anyone who freezes when production opens a shell.
Demo progress: start the first mission to begin tracking.
Shell footing
Read the machine without breaking it. Required clears: 2.
Incident scout
Correlate logs, processes, and disk pressure. Required clears: 5.
Production calm
Explain a safe response under pressure. Required clears: 8.
Mission chain
Step 1
Repair a locked deployment directory
Easy Linux arena: Unix permissions, ownership, and safe read-only inspection
Step 2
Warm up with awk latency report
Easy Bash arena: awk grouping, numeric aggregation, and stable reports
Step 3
Warm up with ripgrep refactor scout
Easy CLI Productivity arena: rg filters, globs, context lines, and machine-readable matches
Step 4
Stabilize runaway process forensics
Medium Linux arena: process inspection with ps, pgrep, lsof, and deterministic filtering
Step 5
Stabilize strict mode deploy script
Medium Bash arena: set -euo pipefail, traps, and explicit error paths
Step 6
Harden journal failure triage
Hard Linux arena: journalctl filtering, time windows, units, and severity levels
Step 7
Harden Kubernetes CrashLoop triage
Hard DevOps Basics arena: pods, logs, events, probes, resource limits, and rollout history
Step 8
Rescue disk pressure hunt
Extreme Linux arena: du, df, sort, and safe cleanup planning
