Bash：以天、时、分、秒显示秒答案

【问题标题】：Bash: Display Seconds in Days, Hours, Minutes, SecondsBash：以天、时、分、秒显示秒
【发布时间】：2021-07-15 00:04:09
【问题描述】：

我有一个函数，灵感来自 here 的 hms，但我希望将其扩展为包括处理和显示 Days。

我已经开始编辑脚本，但很快意识到我在处理逻辑方面已经超出了我的能力范围，将数小时变成数天，反之亦然......

这是我目前所拥有的：

#!/bin/bash

rendertimer(){
    # convert seconds to Days, Hours, Minutes, Seconds
    # thanks to https://www.shellscript.sh/tips/hms/
    local seconds D H M S MM D_TAG H_TAG M_TAG S_TAG
    seconds=${1:-0}
    S=$((seconds%60))
    MM=$((seconds/60)) # total number of minutes
    M=$((MM%60))
    H=$((MM/60))
    D=$((H/24))

    # set up "x day(s), x hour(s), x minute(s) and x second(s)" format
    [ "$D" -eq "1" ] && D_TAG="day" || D_TAG="days"
    [ "$H" -eq "1" ] && H_TAG="hour" || H_TAG="hours"
    [ "$M" -eq "1" ] && M_TAG="minute" || M_TAG="minutes"
    [ "$S" -eq "1" ] && S_TAG="second" || S_TAG="seconds"
    # logic for handling display
    [ "$D" -gt "0" ] && printf "%d %s " $D "${D_TAG},"
    [ "$H" -gt "0" ] && printf "%d %s " $H "${H_TAG},"
    [ "$seconds" -ge "60" ] && printf "%d %s " $M "${M_TAG} and"
    printf "%d %s\n" $S "${S_TAG}"
}

duration=${1}

howlong="$(rendertimer $duration)"
echo "That took ${howlong} to run."

期望的输出

349261 seconds: “运行时间为 4 天 1 小时 1 分 1 秒。”

127932 seconds: “运行时间为 1 天 11 小时 32 分 12 秒。”

86400 seconds: “这需要 1 天才能运行。”

实际输出

349261 seconds: “运行时间为 4 天 97 小时 1 分 1 秒。”

127932 seconds: “运行时间为 1 天 35 小时 32 分 12 秒。”

86400 seconds: “运行时间为 1 天 24 小时 0 分 0 秒。”

谁能帮我解决这个问题？

【解决方案1】：

替换

H=$((MM/60))
D=$((H/24))

到

H=$((MM/60%24))
D=$((MM/60/24))

因此，天数是总分钟数的商，小时数是总分钟数的模数。

另外，你的第二个例子是错误的。 127932 的期望输出是That took 1 day, 11 hours, 32 minutes and 12 seconds to run

感谢@BeardOverflow 和@NikolaySidorov，效果很好：

#!/bin/bash

rendertimer(){
    # convert seconds to Days, Hours, Minutes, Seconds
    # thanks to Nikolay Sidorov and https://www.shellscript.sh/tips/hms/
    local parts seconds D H M S D_TAG H_TAG M_TAG S_TAG
    seconds=${1:-0}
    # all days
    D=$((seconds / 60 / 60 / 24))
    # all hours
    H=$((seconds / 60 / 60))
    H=$((H % 24))
    # all minutes
    M=$((seconds / 60))
    M=$((M % 60))
    # all seconds
    S=$((seconds % 60))

    # set up "x day(s), x hour(s), x minute(s) and x second(s)" language
    [ "$D" -eq "1" ] && D_TAG="day" || D_TAG="days"
    [ "$H" -eq "1" ] && H_TAG="hour" || H_TAG="hours"
    [ "$M" -eq "1" ] && M_TAG="minute" || M_TAG="minutes"
    [ "$S" -eq "1" ] && S_TAG="second" || S_TAG="seconds"

    # put parts from above that exist into an array for sentence formatting
    parts=()
    [ "$D" -gt "0" ] && parts+=("$D $D_TAG")
    [ "$H" -gt "0" ] && parts+=("$H $H_TAG")
    [ "$M" -gt "0" ] && parts+=("$M $M_TAG")
    [ "$S" -gt "0" ] && parts+=("$S $S_TAG")

    # construct the sentence
    result=""
    lengthofparts=${#parts[@]}
    for (( currentpart = 0; currentpart < lengthofparts; currentpart++ )); do
        result+="${parts[$currentpart]}"
        # if current part is not the last portion of the sentence, append a comma
        [ $currentpart -ne $((lengthofparts-1)) ] && result+=", "
    done
    echo "$result"
}

duration=$1
howlong="$(rendertimer "${duration}")"
echo "That took ${howlong} to run."
