PowerShell New-TimeSpan 友好地显示为天（s）小时（s）分钟（s）秒（s）

Question

我一直在寻找类似于 .NET examples 中示例的 PowerShell 脚本。取一个 New-TimeSpan 并显示为 1 天 2 小时 3 分钟 4 秒。排除零的地方，在需要的地方添加复数 "s" 。有人手边有吗？

据我所知：

$StartDate = (Get-Date).ToString("M/dd/yyyy h:mm:ss tt")

Write-Host "Start Time: $StartDate"

# Do Something

$EndDate = (Get-Date).ToString("M/dd/yyyy h:mm:ss tt")

Write-Host "End Time: $EndDate" -ForegroundColor Cyan

$Duration = New-TimeSpan -Start $StartDate -End $EndDate
$d = $Duration.Days; $h = $Duration.Hours; $m = $Duration.Minutes; $s = $Duration.Seconds

Write-Host "Duration: $d Days, $h Hours, $m Minutes, $s Seconds"

Answer 1

为什么不直接这样做呢：

$StartDate = (Get-Date).AddDays(-1).AddMinutes(-15).AddSeconds(-3)
$EndDate = Get-Date

$Duration = New-TimeSpan -Start $StartDate -End $EndDate

$Day = switch ($Duration.Days) {
    0 { $null; break }
    1 { "{0} Day," -f $Duration.Days; break }
    Default {"{0} Days," -f $Duration.Days}
}

$Hour = switch ($Duration.Hours) {
    #0 { $null; break }
    1 { "{0} Hour," -f $Duration.Hours; break }
    Default { "{0} Hours," -f $Duration.Hours }
}

$Minute = switch ($Duration.Minutes) {
    #0 { $null; break }
    1 { "{0} Minute," -f $Duration.Minutes; break }
    Default { "{0} Minutes," -f $Duration.Minutes }
}

$Second = switch ($Duration.Seconds) {
    #0 { $null; break }
    1 { "{0} Second" -f $Duration.Seconds; break }
    Default { "{0} Seconds" -f $Duration.Seconds }
}

"Duration: $Day $Hour $Minute $Second"

输出将是：

Duration: 1 Day, 0 Hours, 15 Minutes, 3 Seconds

持续时间的每个部分有 2 个...

$StartDate = (Get-Date).AddDays(-2).AddHours(-2).AddMinutes(-2).AddSeconds(-2)

结果是这样的：

Duration: 2 Days, 2 Hours, 2 Minutes, 2 Seconds

当然，如果你不止一次需要它，你应该把它包装在一个函数中。 ;-)
当然，如果您愿意，您可以添加更复杂的条件。

table景色还不错：

new-timespan -Days 1 -Hours 1 -Minutes 1 -Seconds 1 | ft

Days Hours Minutes Seconds Milliseconds
---- ----- ------- ------- ------------
1    1     1       1       0
