### Command Patterns & Workflows
|
|
|
|
#### Basic Usage Patterns
|
|
```bash
|
|
# Interactive session
|
|
claude
|
|
|
|
# Quick query
|
|
claude "Explain this error message"
|
|
|
|
# Non-interactive query
|
|
claude -p "Analyze this code structure"
|
|
|
|
# Continue previous conversation
|
|
claude -c
|
|
|
|
# Resume specific session
|
|
claude -r "session-abc123" "Follow up question"
|
|
```
|
|
|
|
#### Piped Input Processing
|
|
```bash
|
|
# Process file content
|
|
cat error.log | claude -p "Analyze these errors"
|
|
|
|
# Process command output
|
|
ls -la | claude -p "Explain this directory structure"
|
|
|
|
# Chain with other tools
|
|
grep "ERROR" app.log | claude -p "Summarize these errors"
|
|
```
|
|
|
|
#### Scripting & Automation
|
|
```bash
|
|
# JSON output for parsing
|
|
claude -p "Get project status" --output-format json
|
|
|
|
# Verbose logging for debugging
|
|
claude -p "Debug this issue" --verbose
|
|
|
|
# Specific model selection
|
|
claude -p "Complex analysis task" --model opus
|
|
```
|
|
|
|
#### Working Directory Management
|
|
```bash
|
|
# Add multiple directories
|
|
claude --add-dir /path/to/project --add-dir /path/to/docs
|
|
|
|
# Start with specific context
|
|
claude --add-dir /home/user/project "Review this codebase"
|
|
```
|
|
|
|
### Tool & Permission Management
|
|
|
|
#### Tool Control
|
|
```bash
|
|
# Allow specific tools only
|
|
claude --allowedTools "Read,Write,Bash" -p "Safe file operations"
|
|
|
|
# Block dangerous tools
|
|
claude --disallowedTools "Bash,Write" "Analyze only, don't modify"
|
|
|
|
# Control agentic behavior
|
|
claude --max-turns 5 "Research this topic"
|
|
```
|
|
|
|
#### Permission Modes
|
|
- **Standard** - Normal permission prompts
|
|
- **Strict** - Enhanced security checks
|
|
- **Permissive** - Reduced friction for trusted environments
|
|
- **Custom** - Use `--permission-prompt-tool` for MCP authentication
|
|
|
|
### Advanced Workflows
|
|
|
|
#### Development Workflow
|
|
```bash
|
|
# Code review session
|
|
claude --add-dir /project/src "Review recent changes"
|
|
|
|
# Debug session with verbose output
|
|
claude --verbose --model sonnet -c
|
|
|
|
# Automated analysis
|
|
cat test-results.xml | claude -p "Generate test report" --output-format json
|
|
```
|
|
|
|
#### Configuration & MCP Setup
|
|
```bash
|
|
# Configure MCP servers
|
|
claude mcp
|
|
|
|
# Use MCP tools with specific permissions
|
|
claude --permission-prompt-tool mcp-auth "Access external APIs"
|
|
```
|
|
|
|
### Best Practices & Optimization
|
|
|
|
#### Performance Tips
|
|
- Use `-p` flag for scripting to avoid interactive overhead
|
|
- Leverage `--output-format json` for programmatic processing
|
|
- Set `--max-turns` to control resource usage in agentic workflows
|
|
- Use `--continue` for efficient conversation resumption
|
|
|
|
#### Security Considerations
|
|
- Review `--allowedTools` settings for production environments
|
|
- Avoid `--dangerously-skip-permissions` in untrusted contexts
|
|
- Use appropriate permission modes for different security levels
|
|
- Validate MCP server configurations before deployment
|
|
|
|
#### Workflow Efficiency
|
|
- Combine `--add-dir` with initial queries for better context
|
|
- Use session resumption for complex, multi-step tasks
|
|
- Leverage piped input for batch processing
|
|
- Set appropriate models based on task complexity
|
|
|
|
### Troubleshooting Guide
|
|
|
|
#### Common Issues
|
|
- **Permission denied errors**: Check `--permission-mode` settings
|
|
- **Tool not found**: Verify `--allowedTools` configuration
|
|
- **Session not found**: Use `claude -c` or check session ID format
|
|
- **Output formatting**: Ensure correct `--output-format` syntax
|
|
|
|
#### Debugging Commands
|
|
```bash
|
|
# Enable verbose logging
|
|
claude --verbose -p "Debug command"
|
|
|
|
# Check current configuration
|
|
claude mcp
|
|
|
|
# Test with minimal permissions
|
|
claude --allowedTools "Read" -p "Safe test query"
|
|
```
|
|
|
|
### Environment Variables & Configuration
|
|
|
|
- **CLAUDE_API_KEY** - Authentication token
|
|
- **CLAUDE_CONFIG_DIR** - Custom configuration directory
|
|
- **CLAUDE_DEFAULT_MODEL** - Default model selection
|
|
- **CLAUDE_LOG_LEVEL** - Logging verbosity
|
|
|
|
### Integration Patterns
|
|
|
|
#### CI/CD Integration
|
|
```bash
|
|
# Automated code review
|
|
claude -p "Review changes in PR #123" --output-format json --max-turns 3
|
|
|
|
# Test result analysis
|
|
pytest --json-report | claude -p "Analyze test failures"
|
|
```
|
|
|
|
#### Shell Integration
|
|
```bash
|
|
# Add to .bashrc/.zshrc
|
|
alias cr='claude -p' # Quick claude review
|
|
alias cc='claude -c' # Continue conversation
|
|
```
