bash脚本:两个时间之间的差别分钟(Bash script: difference in minu

2019-07-18 04:41发布

我有两个时间字符串; 例如。 “9点11”,并在同一天“17点22分”(格式为HH:MM)。 如何计算在这两者之间分钟的时间差?

标准能否date库做到这一点?

例:

#!/bin/bash

MPHR=60    # Minutes per hour.

CURRENT=$(date -u -d '2007-09-01 17:30:24' '+%F %T.%N %Z')
TARGET=$(date -u -d'2007-12-25 12:30:00' '+%F %T.%N %Z')

MINUTES=$(( $(diff) / $MPHR ))

是否有此给出HH小时和分钟做的一个简单的方法:毫米

Answer 1:

纯的bash溶液:

old=09:11
new=17:22

# feeding variables by using read and splitting with IFS
IFS=: read old_hour old_min <<< "$old"
IFS=: read hour min <<< "$new"

# convert hours to minutes
# the 10# is there to avoid errors with leading zeros
# by telling bash that we use base 10
total_old_minutes=$((10#$old_hour*60 + 10#$old_min))
total_minutes=$((10#$hour*60 + 10#$min))

echo "the difference is $((total_minutes - total_old_minutes)) minutes"

另一种采用溶液date (用小时/分钟内有效,日期并不重要)

old=09:11
new=17:22

IFS=: read old_hour old_min <<< "$old"
IFS=: read hour min <<< "$new"

# convert the date "1970-01-01 hour:min:00" in seconds from Unix EPOCH time
sec_old=$(date -d "1970-01-01 $old_hour:$old_min:00" +%s)
sec_new=$(date -d "1970-01-01 $hour:$min:00" +%s)

echo "the difference is $(( (sec_new - sec_old) / 60)) minutes"

Answer 2:

我想转换日期以UNIX时间戳; 你可以减去获得以秒为单位的差异,然后除以60:

#!/bin/bash

MPHR=60    # Minutes per hour.

CURRENT=$(date +%s -d '2007-09-01 17:30:24')
TARGET=$(date +%s -d'2007-12-25 12:30:00')

MINUTES=$(( ($TARGET - $CURRENT) / $MPHR ))


Answer 3:

MPHR=60
CURRENT=09:11
TARGET=17:22
echo $(( ( 10#${TARGET:0:2} - 10#${CURRENT:0:2} ) * MPHR + 10#${TARGET:4} - 10#${CURRENT:4} ))


Answer 4:

这是我如何做的:

START=$(date +%s);
sleep 1; # Your stuff
END=$(date +%s);
echo $((END-START)) | awk '{printf "%d:%02d:%02d", $1/3600, ($1/60)%60, $1%60}'

很简单,拿的秒数在开始,然后采取的秒数末,并打印在几分钟的区别:秒。



Answer 5:

我一直在寻找与秒的解决方案。 这里找到: 如何计算在bash脚本的时间差?

#!/bin/bash
string1="10:33:56"
string2="10:36:10"
StartDate=$(date -u -d "$string1" +"%s")
FinalDate=$(date -u -d "$string2" +"%s")
date -u -d "0 $FinalDate sec - $StartDate sec" +"%H:%M:%S"

在这里,我已经添加秒,吉尔的解决方案:

function countTimeDiff() {
    timeA=$1 # 09:59:35
    timeB=$2 # 17:32:55

    # feeding variables by using read and splitting with IFS
    IFS=: read ah am as <<< "$timeA"
    IFS=: read bh bm bs <<< "$timeB"

    # Convert hours to minutes.
    # The 10# is there to avoid errors with leading zeros
    # by telling bash that we use base 10
    secondsA=$((10#$ah*60*60 + 10#$am*60 + 10#$as))
    secondsB=$((10#$bh*60*60 + 10#$bm*60 + 10#$bs))
    DIFF_SEC=$((secondsB - secondsA))
    echo "The difference is $DIFF_SEC seconds.";

    SEC=$(($DIFF_SEC%60))
    MIN=$((($DIFF_SEC-$SEC)%3600/60))
    HRS=$((($DIFF_SEC-$MIN*60)/3600))
    TIME_DIFF="$HRS:$MIN:$SEC";
    echo $TIME_DIFF;
}


Answer 6:

STARTTIME=$(date +%s)

验证码:

ENDTIME=$(date +%s)
secs=$(($ENDTIME - $STARTTIME))
printf 'Elapsed Time %dh:%dm:%ds\n' $(($secs/3600)) $(($secs%3600/60)) $(($secs%60)) 


Answer 7:

@Dorian
如果你只是想知道一个程序花了多长时间来运行:时间,人,人的时间!

简单的例子:

jonathan@Odin:~$ time sleep 1

real    0m1.001s
user    0m0.000s
sys     0m0.000s

OK,它并没有给结果在几秒钟内,但你可以把它与格式字符串这样做,或者更简单地与POSIX兼容的选项:

jonathan@Odin:~$ time -p sleep 20
real 20.00
user 0.00
sys 0.00
