Bug Reports from User:
1. "line 162: count * 100 / total: division by 0"
2. Empty report - no IP details displayed, only headers
Root Causes:
Issue 1: Division by Zero (line 162)
- show_progress() called with total="unknown"
- Attempted: count * 100 / "unknown" → division error
- Happened when processing logs of unknown size
Issue 2: Empty Report Output
- ALL echo statements used >> "$OUTPUT_FILE" inside { } block
- The { } > "$OUTPUT_FILE" already redirects EVERYTHING to file
- Using >> INSIDE redirected block caused output to go nowhere
- Result: Only headers written, no IP data
Example of broken code (lines 280-390):
{
echo "Header" # Goes to file ✅
echo "Data" >> "$OUTPUT_FILE" # ❌ WRONG! Tries to append while already redirected
} > "$OUTPUT_FILE"
Fixes Applied:
1. show_progress() function (lines 159-168):
Before:
percent=$((count * 100 / total)) # Crashes if total="unknown"
After:
if [ "$total" = "unknown" ] || [ "$total" -eq 0 ]; then
echo "Processing: $count lines..." # No percentage
else
percent=$((count * 100 / total)) # Safe
fi
2. Removed ALL >> "$OUTPUT_FILE" inside output block:
- Used sed to remove 32 instances
- Now all echo statements write to stdout
- The { } > "$OUTPUT_FILE" captures everything correctly
Testing:
Before:
- Division by zero error ❌
- Empty report (no IP details) ❌
After:
- No division errors ✅
- Full report with IP details ✅
- Syntax validated ✅
Impact:
- Report now displays complete IP analysis
- Shows attack types, sample URLs, reputation
- No more math errors during processing
