我有一个功能，灵感来自
这里的
hms，但我希望扩展它以包括处理和显示天数。
我已经开始编辑脚本，但很快意识到我无法处理逻辑，时间长达数小时，反之亦然......
这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 ${howlong} to run."
3492611279328640034926112793286400有人可以帮我解决这个问题吗？
更换
H=$((MM/60))
D=$((H/24))
到
H=$((MM/60%24))
D=$((MM/60/24))
因此，天数是总分钟数的商，小时数是总分钟数的模数。
另外，你的第二个例子是错误的。 127932 的期望输出是
That took 1 day, 11 hours, 32 minutes and 12 seconds to run感谢@BeardOverflow 和@NikolaySidorov，这非常有效：
#!/bin/bash
rendertimer(){
# convert seconds to Days, Hours, Minutes, Seconds
# thanks to Nikolay Sidorov and https://www.shellscript.sh/tips/hms/
local parts seconds D H M S D_TAG H_TAG M_TAG S_TAG
seconds=${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"

[ "$H" -gt "0" ] && parts+=("$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."
我知道这是一篇旧文章，但多一点抽象可以使它更加简洁和灵活，希望参数解析、错误处理和使用说明的示例会对某人派上用场......而且很有趣。
欢迎提出改进建议。
breakout () {

}
这使您可以提供具有不同格式的多个输入，并在发生错误后提供合理合理的默认值。

周数可能不太有用，但很容易添加，因为它是固定的秒数。我没有费心几个月和几年，因为很少需要它们（OP 没有要求几周），并且可能不值得额外的工作来处理不同的长度。
