bash脚本转换毫秒到天：小时：分钟：秒：毫秒 [英] Bash Script to Convert Milliseconds to Days:Hours:Minutes:Seconds:Milliseconds

问题描述

我写了下面的bash脚本，以毫秒为单位转换为天：小时：分钟：秒：毫秒​​，使日志文件更具可读性：

I wrote the following bash script to convert milliseconds to Days:Hours:Minutes:Seconds:Milliseconds to make a log file more readable:

    #!/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

输入文件的部分：

Section of Input File:

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

有输出表明，它不能正常工作的几行：

There are several lines of output that shows that it is not working correctly:

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

几个小时后故障排除我无法找到我的错误。任何帮助将是非常美联社preciated。

After several hours of troubleshooting I am unable to find my error. Any help would be much appreciated.

推荐答案

拆分为毫秒级和第二，使用GNU日期，你应该比较容易得到的结果。

Split into millisecond and second, using GNU date, you should be easier to get the result

#!/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
