[日期时间] 求助批处理解析TXT文本里的时间并计算成分钟数

smtcao008

如下是3DMARK产生的3D.txt，想实现监控其跑的时间长短，理论是第一行时间和末尾行时间相减得出分钟数，这种批处理能实现吗？

很丑很不严谨

$txt = gc .\a.txt; ((Get-Date (($txt | select -Last 1) -split ' ')[0])-(Get-Date (($txt | select -First 1) -split ' ')[0])).TotalMinutes

    请把txt文件上传到网盘，以便测试代码，直接发出来文本内容在格式上可能会有变化。

我临时还使用最简陋的指令抓loop数先管控！~~~

改了下，文件名换成了网盘文件的3d.log（不是1楼的3d.txt）
分钟结果保留了4位小数，只要时间都是2位数字的，并且都符合格式的，1天之内应该也许大概都没问题？（不包括1天）

@echo off

set "file=3d.log"

for /f "tokens=1 delims= " %%a in ('findstr /b "[0-9]" "%file%"') do (
if not defined first set first=%%a
set last=%%a
)

setlocal enabledelayedexpansion
for /f "tokens=1-3 delims=:" %%a in ("!first!") do set /a m=1%%a*3600+1%%b*60+1%%c
for /f "tokens=1-3 delims=:" %%a in ("!last!") do set /a n=1%%a*3600+1%%b*60+1%%c
set /a "t1=n-m"
if !t1! lss 0 (
set /a t1=24*3600+t1
)
set /a t2=t1%%60

以下是用第3方工具gawk（http://bcn.bathome.net/tool/4.1.0/gawk.exe）的实现方式

命令行方式（单百分号%）

gawk "$1~/([0-1]?[0-9]|2[0-3]):([0-5][0-9]):([0-5][0-9])/{split($1,a,/:/);t2=(a[1]*60+a[2])*60+a[3];if(!r){t1=t2;r=1}}END{printf(\"hh:mm:ss %02d:%02d:%02d\",(t2-t1)/3600,(t2-t1)%3600/60,(t2-t1)%60)}" 3d.log
复制代码

bat脚本方式（双百分号%%）

gawk "$1~/([0-1]?[0-9]|2[0-3]):([0-5][0-9]):([0-5][0-9])/{split($1,a,/:/);t2=(a[1]*60+a[2])*60+a[3];if(!r){t1=t2;r=1}}END{printf(\"hh:mm:ss %%02d:%%02d:%%02d\",(t2-t1)/3600,(t2-t1)%%3600/60,(t2-t1)%%60)}" 3d.log
