# Bash Scripting Workflow

## Overview

Specialized workflow for creating robust, production-ready bash scripts with defensive programming patterns, comprehensive error handling, and automated testing.

## When to Use This Workflow

Use this workflow when:
- Creating automation scripts
- Writing system administration tools
- Building deployment scripts
- Developing backup solutions
- Creating CI/CD scripts

## Workflow Phases

### Phase 1: Script Design

#### Skills to Invoke
- `bash-pro` - Professional scripting
- `bash-defensive-patterns` - Defensive patterns

#### Actions
1. Define script purpose
2. Identify inputs/outputs
3. Plan error handling
4. Design logging strategy
5. Document requirements

#### Copy-Paste Prompts
```
Use @bash-pro to design production-ready bash script
```

### Phase 2: Script Structure

#### Skills to Invoke
- `bash-pro` - Script structure
- `bash-defensive-patterns` - Safety patterns

#### Actions
1. Add shebang and strict mode
2. Create usage function
3. Implement argument parsing
4. Set up logging
5. Add cleanup handlers

#### Copy-Paste Prompts
```
Use @bash-defensive-patterns to implement strict mode and error handling
```

### Phase 3: Core Implementation

#### Skills to Invoke
- `bash-linux` - Linux commands
- `linux-shell-scripting` - Shell scripting

#### Actions
1. Implement main functions
2. Add input validation
3. Create helper functions
4. Handle edge cases
5. Add progress indicators

#### Copy-Paste Prompts
```
Use @bash-linux to implement system commands
```

### Phase 4: Error Handling

#### Skills to Invoke
- `bash-defensive-patterns` - Error handling
- `error-handling-patterns` - Error patterns

#### Actions
1. Add trap handlers
2. Implement retry logic
3. Create error messages
4. Set up exit codes
5. Add rollback capability

#### Copy-Paste Prompts
```
Use @bash-defensive-patterns to add comprehensive error handling
```

### Phase 5: Logging

#### Skills to Invoke
- `bash-pro` - Logging patterns

#### Actions
1. Create logging function
2. Add log levels
3. Implement timestamps
4. Configure log rotation
5. Add debug mode

#### Copy-Paste Prompts
```
Use @bash-pro to implement structured logging
```

### Phase 6: Testing

#### Skills to Invoke
- `bats-testing-patterns` - Bats testing
- `shellcheck-configuration` - ShellCheck

#### Actions
1. Write Bats tests
2. Run ShellCheck
3. Test edge cases
4. Verify error handling
5. Test with different inputs
