**Recommendation**: Standardize on `#!/usr/bin/env bash` for better portability

**Priority**: Medium  
**Effort**: Low  
**Impact**: Medium

**Action Items**:
```bash
# Create script to standardize shebangs
find scripts -name "*.sh" -type f -exec sed -i '1s|#!/bin/bash|#!/usr/bin/env bash|' {} \;
```

### 1.2 Error Handling Standardization

**Issue**: Inconsistent error handling flags
- Some scripts use `set -e`
- Some use `set -euo pipefail`
- Some have no error handling

**Recommendation**: Standardize on `set -euo pipefail` for all scripts

**Priority**: High  
**Effort**: Medium  
**Impact**: High

**Action Items**:
1. Create script to audit and update error handling
2. Add error handling to scripts missing it
3. Document error handling best practices

#!/usr/bin/env bash
set -euo pipefail

# Script-specific error handling
trap 'error_exit "Line $LINENO: Command failed"' ERR
trap 'cleanup_on_exit' EXIT
```
