# OS/Shell Scripting Troubleshooting Workflow Bundle

## Overview

Comprehensive workflow for operating system troubleshooting, shell scripting, and system administration across Linux, macOS, and Windows. This bundle orchestrates skills for debugging system issues, creating robust scripts, and automating administrative tasks.

## When to Use This Workflow

Use this workflow when:
- Debugging shell script errors
- Creating production-ready bash scripts
- Troubleshooting system issues
- Automating system administration tasks
- Managing processes and services
- Configuring system resources

## Workflow Phases

### Phase 1: Environment Assessment

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

#### Actions
1. Identify operating system and version
2. Check available tools and commands
3. Verify permissions and access
4. Assess system resources
5. Review logs and error messages

#### Diagnostic Commands
```bash
# System information
uname -a
cat /etc/os-release
hostnamectl

# Resource usage
top
htop
df -h
free -m

# Process information
ps aux
pgrep -f pattern
lsof -i :port

# Network status
netstat -tulpn
ss -tulpn
ip addr show
```

#### Copy-Paste Prompts
```
Use @bash-linux to diagnose system performance issues
```

### Phase 2: Script Analysis

#### Skills to Invoke
- `bash-defensive-patterns` - Defensive scripting
- `shellcheck-configuration` - ShellCheck linting
- `bats-testing-patterns` - Bats testing

#### Actions
1. Run ShellCheck for linting
2. Analyze script structure
3. Identify potential issues
4. Check error handling
5. Verify variable usage

#### ShellCheck Usage
```bash
# Install ShellCheck
sudo apt install shellcheck  # Debian/Ubuntu
brew install shellcheck      # macOS

# Run ShellCheck
shellcheck script.sh
shellcheck -f gcc script.sh

# Fix common issues
# - Use quotes around variables
# - Check exit codes
# - Handle errors properly
```

#### Copy-Paste Prompts
```
Use @shellcheck-configuration to lint and fix shell scripts
```

### Phase 3: Debugging

#### Skills to Invoke
- `systematic-debugging` - Systematic debugging
- `debugger` - Debugging specialist
- `error-detective` - Error pattern detection

#### Actions
1. Enable debug mode
2. Add logging statements
3. Trace execution flow
4. Isolate failing sections
5. Test components individually

#### Debug Techniques
```bash
# Enable debug mode
set -x  # Print commands
set -e  # Exit on error
set -u  # Exit on undefined variable
set -o pipefail  # Pipeline failure detection

# Add logging
log() {
    echo "[$(date '+%Y-%m-%d %H:%M:%S')] $*" >> /var/log/script.log
}

# Trap errors
trap 'echo "Error on line $LINENO"' ERR

# Test sections
bash -n script.sh  # Syntax check
bash -x script.sh  # Trace execution
```

#### Copy-Paste Prompts
```
Use @systematic-debugging to trace and fix shell script errors
```

### Phase 4: Script Development

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

#### Actions
1. Design script structure
2. Implement functions
3. Add error handling
4. Include input validation
5. Add help documentation

#### Script Template
```bash
#!/usr/bin/env bash
set -euo pipefail

# Constants
readonly SCRIPT_NAME=$(basename "$0")
readonly SCRIPT_DIR=$(cd "$(dirname "$0")" && pwd)

# Logging
log() {
    local level="$1"
    shift
    echo "[$(date '+%Y-%m-%d %H:%M:%S')] [$level] $*" >&2
}

info() { log "INFO" "$@"; }
warn() { log "WARN" "$@"; }
error() { log "ERROR" "$@"; exit 1; }

# Usage
usage() {
    cat <<EOF
Usage: $SCRIPT_NAME [OPTIONS]

Options:
    -h, --help      Show this help message
    -v, --verbose   Enable verbose output
    -d, --debug     Enable debug mode

Examples:
    $SCRIPT_NAME --verbose
    $SCRIPT_NAME -d
EOF
}

# Main function
main() {
    local verbose=false
    local debug=false

    while [[ $# -gt 0 ]]; do
        case "$1" in
            -h|--help)
                usage
                exit 0
                ;;
            -v|--verbose)
                verbose=true
                shift
                ;;
            -d|--debug)
                debug=true
                set -x
                shift
                ;;
            *)
                error "Unknown option: $1"
                ;;
        esac
    done

    info "Script started"
    # Your code here
    info "Script completed"
}

main "$@"
```

#### Copy-Paste Prompts
