cchistory

npm version

Like the shell history command but for your Claude Code sessions.

Why cchistory?

When Claude Code runs shell commands, they don't appear in your shell history. This makes it hard to:

  • Re-run useful commands from past sessions
  • Build on previous work
  • Learn from command patterns Claude uses
  • Copy command sequences for documentation
$ cchistory | tail -5
  46  git status
  47  git pull origin main
  48  git log --oneline -5
  49  docker-compose up -d
  50  curl -I localhost:8080/health

📦 Installation

npm (recommended)

npm install -g cchistory

npx (try without installing)

npx cchistory --help

From source

git clone https://github.com/eckardt/cchistory
cd cchistory
npm install
npm run build
npm link

Usage

cchistory                    # Current project history
cchistory --global           # All projects
cchistory --list-projects    # See all available projects
cchistory | grep docker      # Find Docker commands  
cchistory | tail -5          # Last 5 commands
cchistory my-app | tail -10  # Last 10 from specific project
cchistory ~/code/my-app      # Project by full path

✨ Features

  • 🔍 Extract all Bash commands Claude executed across projects
  • 🗂️ Filter by specific project or search globally
  • 📊 Standard Unix tool compatibility (grep, awk, sort)
  • ⚡ Fast streaming parser for large conversation logs
  • 🚀 Zero-config - works with existing Claude Code setup

How It Works

Claude Code stores conversation history in ~/.claude/projects/. This tool:

  1. Finds your Claude projects
  2. Streams through conversation logs
  3. Extracts shell commands Claude executed
  4. Formats them like traditional shell history

📋 Example Output

$ cchistory --global | head -10
   1  [web-scraper    ] npm install puppeteer
   2  [web-scraper    ] mkdir src tests
   3  [api-project    ] docker-compose up -d
   4  [api-project    ] curl -X POST localhost:3000/api/test
   5  [frontend       ] npm run dev
   6  [frontend       ] git add .
   7  [backend        ] npm test
   8  [backend        ] git commit -m "fix: validation"
   9  [deployment     ] kubectl apply -f deployment.yaml
  10  [deployment     ] kubectl get pods

Advanced Usage

# Find all npm commands across projects
cchistory --global | grep npm

# Get last 20 Docker commands
cchistory --global | grep docker | tail -20

# Count commands by type
cchistory --global | sed 's/.*] //' | awk '{print $1}' | sort | uniq -c | sort -nr | head -10

Command Sources

Extracts commands from:

  • Bash tool usage: Commands Claude executes via the Bash tool
  • User "!" commands: Commands you run with ! command in Claude

Requirements

  • Node.js 20+
  • Claude Code with conversation history in ~/.claude/projects/

Note: Claude Code automatically cleans up conversation transcripts based on the cleanupPeriodDays setting (default: 30 days). Commands older than this period won't appear in cchistory output. You can adjust this retention period in Claude Code's settings if needed.

Options

cchistory [project-name]    # Show history for specific project (by name or path)
cchistory --global          # Show history from all projects  
cchistory --list-projects   # List all available Claude projects
cchistory --help            # Show usage info

Output Format

Each line shows:

[sequence] [project-name] command
  • sequence: Command number (oldest first)
  • project-name: Which Claude project ran the command
  • command: The actual shell command

Multi-line commands use zsh history format with \\n for newlines.

Unix Philosophy

cchistory does one thing well: extract shell commands. Use it with standard Unix tools:

  • grep for filtering
  • head/tail for limiting output
  • awk for field processing
  • sort/uniq for analysis
  • Pipe to files for documentation
