将毫秒转换为天的 Bash 脚本 :Hours:Minutes:Seconds:Milliseconds

Question

我编写了以下 bash 脚本将毫秒转换为 Days:Hours:Minutes:Seconds:Milliseconds 以使日志文件更具可读性:

    #!/bin/bash
    ### Constants ###
    CON_DAYS=.0000000115741
    CON_HOURS=.000000277778
    CON_MINUTES=.000066667
    CON_SECONDS=.001

    ### Variables ###
    INPUT="$1"

    cat $INPUT | awk -v CON_HOURS=$CON_HOURS -v CON_MINUTES=$CON_MINUTES -v CON_SECONDS=$CON_SECONDS -v CON_DAYS=$CON_DAYS '
        { $1=substr($0,0,10) }
        { MILLISECONDS = $1 }
        { DAYS = int(MILLISECONDS * CON_DAYS) }
        { MILLISECONDS = MILLISECONDS - int( DAYS / CON_DAYS ) }
        { HOURS = int(MILLISECONDS * CON_HOURS) }
        { MILLISECONDS = MILLISECONDS - int(HOURS / CON_HOURS) }
        { MINUTES = int(MILLISECONDS * CON_MINUTES) }
        { MILLISECONDS = MILLISECONDS - int(MINUTES / CON_MINUTES) }
        { SECONDS = int(MILLISECONDS * CON_SECONDS) }
        { MILLISECONDS = MILLISECONDS - int( SECONDS / CON_SECONDS ) }
        { $1 = DAYS":"HOURS":"MINUTES":"SECONDS":"MILLISECONDS"ms" }
        {print}'
    exit

输入文件部分:

1882224617mS ATMChannel: [1] CMLinkLayer Rx: 'DialDigits' (ls)
1882224617mS ATMIO:      [1] TONE DIAL (11 digits)
1882224617mS ATMChannel: [1] StateChange Connected->ToneDialing

有几行输出表明它工作不正常:

22:19:224:14:186ms ATMChannel: [1] CMLinkLayer Rx: 'DialDigits' (ls)
22:19:224:14:186ms ATMIO: [1] TONE DIAL (11 digits)
22:19:224:14:186ms ATMChannel: [1] StateChange Connected->ToneDialing

经过几个小时的故障排除后，我无法找到我的错误。任何帮助将不胜感激。

分为毫秒和秒，使用GNU日期，你应该更容易得到结果

#!/bin/bash

INPUT="$1"

while read t rest
do
  ms=$(echo $t|sed -r "s/.*(.....)$/\1/")  # get Milliseconds  617mS
  se=$(echo $t|sed -r "s/(.....)$//")      # get seconds  1882224
  days=$(echo $se / 3600 / 24 |bc)

  d="$days:$(date -d "1970-01-01 $se seconds" +%H:%M:%S):$ms"
  echo "$d $rest"
done < $INPUT
