# chrome-error-scan.sh - scan per-profile chrome logs for concerning patterns.
|
|
# Self-contained: scans, compares against watermark, reports only NEW matches.
|
|
#
|
|
# Usage: chrome-error-scan.sh [--json]
|
|
# Default output: "profile:new_count" lines for profiles with new matches,
|
|
# or "OK: no new errors" if clean.
|
|
# --json: output JSON {"profile": {"total": N, "new": M}, ...}
|
|
#
|
|
# Watermark: /home/super/Projects/NetVM/chrome-error-watermark.json
|
|
# Patterns: FATAL, crash, segfault, out of memory (case-insensitive)
