Debug

Error tracing, log analysis, memory leak detection, HTTP debugging, and command profiling — all from the command line. Analyze log files for error patterns, parse stack traces from Python/Java/Go/JS crash dumps, monitor process memory for leaks, benchmark command execution, compare log files side-by-side, and debug HTTP endpoints with timing and SSL inspection.

Commands

trace — Find error patterns in log files

Scans a log file for error-level patterns (ERROR, FATAL, Exception, Traceback, WARN, OOM, Segfault, panic, SIGKILL, SIGSEGV). Shows match count, error breakdown by type, last 20 matching lines, and top 10 unique error patterns (with timestamps and addresses normalized for dedup).

bash scripts/script.sh trace /var/log/app.log
bash scripts/script.sh trace --pattern "OOM\|Segfault\|FATAL" /var/log/syslog
bash scripts/script.sh trace --last 1h /var/log/app.log
bash scripts/script.sh trace --last 2d --pattern "Exception" application.log
