我想要一个 powershell 脚本，从中我从 csv 文件中提取几行到另一个 csv 并计算整个列时间值

Question

这是我在 csv 文件中的数据

"Day","Person","Start","End","Elapsed"
"2022-10-12","121   ","08:03","18:04","10h, 01m, 06s"
"2022-10-12","sajjad   ","15:38","22:59","07h, 21m, 22s"
"2022-10-13","121   ","08:06","18:25","10h, 19m, 09s"
"2022-10-13","sajjad   ","08:37","16:02","07h, 24m, 51s"
"2022-10-13","128   ","08:27","17:33","09h, 06m, 34s"
"2022-10-13","140   ","09:02","09:03","00h, 01m, 08s"
"2022-10-17","114   ","08:12","14:58","06h, 46m, 37s"
"2022-10-17","sajjad   ","14:08","23:57","09h, 48m, 40s"
"2022-10-17","128   ","08:30","12:23","03h, 53m, 34s"
"2022-10-17","133   ","08:17","08:19","00h, 02m, 30s"

我想用工作时间计算提取包含人“sajjad”字的整行，我想要的输出是这样的：

"Day","Person","Start","End","Elapsed","employee working hours minutes secs"
"2022-10-12","sajjad   ","15:38","22:59","07h, 21m, 22s"
"2022-10-13","sajjad   ","08:37","16:02","07h, 24m, 51s"
"2022-10-17","sajjad   ","14:08","23:57","09h, 48m, 40s","24hrs 34 mints 33"

我用了这个脚本

$log = get-content "C:\Users\NOC-Notebook\Desktop\export.csv"

foreach ($line in $log) { 
    if (($line -like '*sajjad*') )
    {
    $line | out-file -FilePath "C:\Users\NOC-Notebook\Desktop\export1.txt" -Append
    }
}   

但没有得到适当的结果，从这段代码中只得到单列中的人 sajjad 行而不计算，任何帮助将不胜感激。

Answer 1

正如已经指出的那样——如果你有一个正确的 CSV 文件，你应该这样对待它。

基本上应该是你所需要的：

Import-Csv -Path 'C:UsersNOC-NotebookDesktopexport.csv' |
    Where-Object -Property 'Person' -Match -Value 'sajjad'

如果要将其保存到文件中，请添加管道并

    Export-Csv -Path 'C:UsersNOC-NotebookDesktopexport1.txt' -NoTypeInformation

编辑：
如果我根据您的附加评论说对了，您想总结“sajjad”的工作时间，对吗？但是按照您在问题中显示的方式进行操作会导致 CSV 无效。

如果您只对结果感兴趣，您可以使用计算属性来计算每天的工作时间，并在以后通过循环对其进行总结。

输入数据

$InputData = @'
"Day","Person","Start","End","Elapsed"
"2022-10-12","121   ","08:03","18:04","10h, 01m, 06s"
"2022-10-12","sajjad   ","15:38","22:59","07h, 21m, 22s"
"2022-10-13","121   ","08:06","18:25","10h, 19m, 09s"
"2022-10-13","sajjad   ","08:37","16:02","07h, 24m, 51s"
"2022-10-13","128   ","08:27","17:33","09h, 06m, 34s"
"2022-10-13","140   ","09:02","09:03","00h, 01m, 08s"
"2022-10-17","114   ","08:12","14:58","06h, 46m, 37s"
"2022-10-17","sajjad   ","14:08","23:57","09h, 48m, 40s"
"2022-10-17","128   ","08:30","12:23","03h, 53m, 34s"
"2022-10-17","133   ","08:17","08:19","00h, 02m, 30s"
'@ | 
ConvertFrom-Csv

将工作时间添加为时间跨度值

$Result = 
$InputData |
Where-Object -Property 'Person' -Match -Value 'sajjad' |
Select-Object -Property *,
@{
    Name       = 'WorkingHours'
    Expression = {
        New-TimeSpan -Start $_.Start -End $_.End
    }
}

计算总和

$Result |
    ForEach-Object {
        $WorkingHoursSum += $_.WorkingHours
    }
$WorkingHoursSum

如果需要，您可以使用结果进行计算。为了提高可读性，您可以根据需要格式化输出。例如像这样：

'sajjad worked {0:n0} hours and {1} minutes in total.' -f $WorkingHoursSum.TotalHours, $WorkingHoursSum.Minutes

Answer 2

我终于做对了。时间跨度不起作用，因为开始时间和结束时间没有秒数。
