5 Bash one-liners for debugging flaky CI logs

- Find first failure:
grep -n -m1 -iE "error|fail" build.log - Context around it:
grep -n -B5 -A15 -m1 -iE "error|fail" build.log - Count repeated errors:
grep -iE "error" build.log | sed -E 's/[0-9]+/N/g' | sort | uniq -c | sort -rn | head - Time gaps (hangs):
awk '{print $1}' build.log | uniq -c | sort -rn | head - Compare passing vs failing run:
diff <(sed -E 's/[0-9:.-]+//g' ok.log) <(sed -E 's/[0-9:.-]+//g' bad.log) | head -50
