command -v gemini || which gemini
gemini "[prompt]" --yolo -o text 2>&1
Key flags:
--yolo or -y: Auto-approve all tool calls-o text: Human-readable output-o json: Structured output with stats-m gemini-2.5-flash: Use faster model for simple tasksYOLO Mode Behavior: Auto-approves tool calls but does NOT prevent planning prompts. Gemini may still present plans and ask "Does this plan look good?" Use forceful language:
Rate Limits: Free tier has 60 requests/min, 1000/day. CLI auto-retries with backoff. Expect messages like "quota will reset after Xs".
For JSON output (-o json), parse:
{
"response": "actual content",
"stats": {
"models": { "tokens": {...} },
"tools": { "byName": {...} }
}
}
gemini "Create [description] with [features]. Output complete file content." --yolo -o text
gemini "Review [file] for: 1) features, 2) bugs/security issues, 3) improvements" -o text
gemini "Fix these bugs in [file]: [list]. Apply fixes now." --yolo -o text

gemini "What are the latest [topic]? Use Google Search." -o text
gemini "[prompt]" -m gemini-2.5-flash -o text
-m gemini-2.5-flash for lower priority tasksgemini --version~/.gemini/settings.json for config issuesAlways verify Gemini's output:
# 1. Generate
gemini "Create [code]" --yolo -o text
# 2. Review (Gemini reviews its own work)
gemini "Review [file] for bugs and security issues" -o text
# 3. Fix identified issues
gemini "Fix [issues] in [file]. Apply now." --yolo -o text
For long tasks, run in background and monitor:
gemini "[long task]" --yolo -o text 2>&1 &
# Monitor with BashOutput tool
These tools are available only through Gemini:
Create .gemini/GEMINI.md in project root for persistent context that Gemini will automatically read.
List sessions: gemini --list-sessions
Resume session: echo "follow-up" | gemini -r [index] -o text
