Bash：以天、小时、分钟、秒为单位显示秒

Question

我有一个函数，受hms的启发，但我希望将其扩展到包括处理和显示天数。

我已经开始编辑脚本，但很快意识到我在处理逻辑方面超出了我的深度，几个小时跑到几天，反之亦然......

以下是我到目前为止所拥有的：

#!/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."

349261秒：“那花了4天1小时1分1秒才运行。”

< code>127932秒:“运行时间为1天11小时32分12秒。”

< code>86400秒:“花了1天时间运行。”

349261秒：“这花了4天97小时1分1秒才运行。

127932秒：“运行时间为1天35小时32分12秒。”

86400秒：“那需要1天24小时0分0秒才能运行。”

有人能帮我弄清楚吗？

感谢@BeardOverflow和@NikolaySidorov，这非常有效：

#!/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."

代替

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

到

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

所以，天数是你总时间的商，小时是你总时间的模数。

另外，你的第二个例子是错误的。127932的期望输出是需要1天11小时32分12秒才能运行
