如何在脚本中复制一系列日期的数据？

尽管这不是一个代码编写服务，但它听起来像是您对该语言的新手，所以这里有些东西可以帮助您完成此任务。在将来，我建议你添加一些你已经试过的代码，因为你可能会得到更多的回应。

# Get-Date is a cmdlet in PowerShell to get the current date 
# We use AddDays(-5) to subtract however many days we would like. Here we are subtracting 5 days from current date 
# ToString converts the data type so that we can use the custom date format of yyyyMMdd 
$Date = (Get-Date).AddDays(-5).ToString('yyyyMMdd') 
# Get-Item cmdlet in PowerShell is used to get files in a directory 
# Select allows us to get a specific piece of data from the files found and ExpandProperty hides the data header 
$Files = Get-Item -Path C:\Temp\*$Date.txt | Select -ExpandProperty FullName 
# Copies Files Found with Get-Item 
Copy-Item -Path $Files -Destination C:\SomePathHere-Verbose -Force 

输出将如下所示：

PS C:\> $Date = (Get-Date).AddDays(-5).ToString('yyyyMMdd') 
# What is stored in $Date variable 
PS C:\> $Date 
20160708 
PS C:\> $Files = Get-Item -Path C:\Temp\*$Date.txt | Select -ExpandProperty FullName 
# What is stored in $Files variable 
PS C:\> Get-Item -Path C:\Temp\*$Date.txt | Select -ExpandProperty FullName 
C:\Temp\Somefile20160708.txt 
C:\Temp\SomeOtherFile20160708.txt 
PS C:\> Copy-Item -Path $Files -Destination C:\Test -Verbose -Force 
VERBOSE: Performing the operation "Copy File" on target "Item: C:\Temp\Somefile20160708.txt Destination: C:\Test\Somefile20160708.txt". 
VERBOSE: Performing the operation "Copy File" on target "Item: C:\Temp\SomeFile220160708.txt Destination: C:\Test\SomeOtherFile220160708.txt". 

希望这有助于你达成解决方案。 PowerShell非常适合这些类型的任务，我绝对建议您进一步探索它。
