使用 Powershell Get-ChildItem 移动具有特定日期的文件

Question

Need some help with a powershell script. I need to move files by a specific last modified date with similar names. Here is the script I tried running and it just hangs...

$SourceFolder = "C:\documents\testing123.txt" 

$targetFolder = "D:\documents"   

Get-ChildItem -Path $SourceFolder -Filter E0100* | where-object {$_.LastWriteTime -eq ("08/01/2015") | move-item -destination $targetFolder

Answer 1

Since, LastWriteTime is a DateTime the -ge in comparing an exact time. Here is an example that copies using a date range that I believe you desire.

$SourceFolder = "C:\documents\testing123.txt" 

$targetFolder = "D:\documents"   
$startTime =[DateTime]"08/01/2015"
$endTime = $startTime.AddDays(1)
Get-ChildItem -Path $SourceFolder -Filter E0100* | 
     Where-Object {$_.LastWriteTime -ge $startTime -and $_.LastWriteTime -lt $endTime} | 
     Move-Item -destination $targetFolder

As others have mentioned, the source folder path seems incorrect.

Here is a robocopy version of the script I tried (date, paths, and filter have been changed)

$SourceFolder = "D:\test" 

$targetFolder = "D:\test2"   
$startTime =[DateTime]"01/05/2017"
$endTime = $startTime.AddDays(1)
$files = @()
Get-ChildItem -Path $SourceFolder -Filter * | 
     Where-Object {$_.LastWriteTime -ge $startTime -and $_.LastWriteTime -lt $endTime -and $_.Attributes -ne 'Directory'} | 
     ForEach-Object { $files += $_.Name}

if($files.Count -gt 0)
{
  Write-Verbose "running robocopy $SourceFolder $targetFolder $files /mov" -Verbose
  robocopy $SourceFolder $targetFolder $files /mov
}

This is a simple two-line PowerShell that will get move your files by date and file type. You can change the Move-Item to Copy-Item if you do not want to move them.

$Now=Get-Date

Get-ChildItem E:\scripts\logs\*.txt | Where-Object { $_.LastWriteTime -lt $Now.AddDays(-7) } | Move-Item -Destination E:\scripts\logs\Archive\7Days
