Start Interactive LessonPremium: Bash Incident Drill
You are the on-call engineer. Build a safe release sandbox, isolate build errors, and quantify damage.
Step 1: Prepare a Safe Workspace
Command Prompt
app
C:\Users\User>ls
This creates a disposable copy so investigation never touches the original folder.
Step 2: Extract Errors from Build Logs
Command Prompt
INFO compile step started
ERROR missing env var
WARN fallback cache used
ERROR migration timeout
C:\Users\User>cat release/app/build.log
Step 3: Verify Incident Size
Command Prompt
ERROR missing env var
ERROR migration timeout
C:\Users\User>cat release/errors.log
Checklist You Can Reuse
- Stage with
mkdir -p+cp -r. - Isolate critical lines with
grep. - Quantify impact with
wc -l.
