CRITICAL FIXES: 1. Add mktemp temp directory - replaced all hardcoded /tmp/ paths with secure $TEMP_DIR 2. Add cleanup trap (EXIT/INT/TERM) - automatically cleans up temp files on exit/interrupt 3. Replace all /tmp/*.* references - prevents accumulation of temp files 4. Add error handling on critical operations - cp, awk, tail, wc operations now fail-safe 5. Fix division by zero - max_vol now defaults to 1 to prevent arithmetic errors 6. Fix grep regex injection - domain variable now escaped for safe use in patterns BEST PRACTICES: 7. Quote all $TEMP_DIR variable references - prevents word splitting issues 8. Quote unquoted variables in echo - properly quote $issue in loop 9. Add file existence checks - verify temp files exist before reading 10. Replace inline read with press_enter() - follows toolkit standards ERROR HANDLING IMPROVEMENTS: - cp operation: now exits with error message on failure - awk filtering: now exits with error message on failure - tail fallback: now exits with error message on failure - Final log verification: confirms $TEMP_LOG has content before analysis SECURITY: - Removed dangerous /tmp/*.* cleanup pattern - Escaped domain strings in grep patterns to prevent regex injection - All temporary files now isolated in secure mktemp directory - Trap handler ensures cleanup even on interrupt VERIFIED: ✅ Syntax validation: PASS ✅ All critical errors fixed ✅ Properly quoted all variables ✅ Error handling on file operations ✅ Cleanup trap configured ✅ Escape sequences safe
