🔍 Log Pattern Search with Context

Find errors across multiple log files in seconds

Search multiple log files for patterns with surrounding context lines. Smart time-range filtering, case-insensitive option, and color output make debugging much faster than grep + manual context-finding.

Features

  • ✅ Search across multiple log files in one go
  • ✅ Configurable context lines before/after each match
  • ✅ Time-range filter (-s 1h, -s 24h, -s 7d)
  • ✅ Case-insensitive search
  • ✅ Color-coded output, grouped by file

Usage

./log-tail-search.sh -p "Out of memory" -d /var/log
./log-tail-search.sh -p "Failed password" -s 24h -i
./log-tail-search.sh -p "error" -f syslog,messages -n 5
