获取时间平均值的awk脚本

/..:..:..\./ {
  ++count
  split($0,a,":");
  seconds = (a[1] * 60.0 + a[2]) * 60.0 + a[3]
  print $0, seconds
  alltime += seconds
}
END {
  if (count > 0) {
    avgtime = alltime / count
    print count, alltime, avgtime
    mins = int(avgtime / 60.0) % 60
    hours = int(avgtime / 60.0 / 60.0)
    secs = avgtime % 60.0
    printf("%02d:%02d:%05.2f\n", hours, mins, secs)
  }
}
