Powershell脚本根据修改日期复制文件以检查远程位置的最新文件 [英] Powershell Script to copy files based on date modifed to check newest file from a remote location

问题描述

我是 powershell 脚本的新手，我不知道为什么我的脚本会复制所有文件，似乎没有检查日期，然后复制所有文件反正.我也试图按天分分钟做，但我不太确定关于如何做到这一点.任何帮助都会很棒！

I am new to powershell scripting and i cant figure out why my script copies all files and doesn't seem to check the date and then copies all the files anyway. I was trying to do by days and minutes too, but I am not quite sure on how to do that. any help would be great!

see my script below.

$RemotePath = "\eb-pcE$	estlocation*.txt"
$LocalPath = "C:	estlocation"
$Max_days = "-1"
#Max_mins = "-5"
$Curr_date = get-date

#Checking date and then copying file from RemotePath to LocalPath
Foreach($file in (Get-ChildItem $RemotePath))
{
    if($file.LastWriteTime -gt ($Curr_date).adddays($Max_days))
    {
        Copy-Item -Path $file.fullname -Destination $LocalPath
        #Move-Item -Path $file.fullname -Destination $LocalPath
    }

}

推荐答案

如果要使用小时和分钟，而不是 AddDays，只需使用 .AddMinutes()、.AddHours() 或 .AddSeconds() 方法.

If you want to use Hours and minutes, instead of AddDays, just use the .AddMinutes(), .AddHours(), or .AddSeconds() methods instead.

为了它的价值，我做了一个小的修改，在脚本中添加了一个 Else{Scriptblock} 来回显那些没有被复制的文件.正如所写的那样，您的代码只会复制过去 24 小时内编写的文件.

For what it's worth, I made a small modifcation, adding an Else{Scriptblock} to the script to echo out the files which aren't being copied. As written your code will only copy files written in the last 24 hours.

$RemotePath = "t:"
$LocalPath = "C:	emp"
$Max_days = "-1"
#Max_mins = "-5"
$Curr_date = get-date

#Checking date and then copying file from RemotePath to LocalPath
Foreach($file in (Get-ChildItem $RemotePath))
{
    if($file.LastWriteTime -gt ($Curr_date).adddays($Max_days))
    {

        Copy-Item -Path $file.fullname -Destination $LocalPath -WhatIf
        #Move-Item -Path $file.fullname -Destination $LocalPath
    }
    ELSE
    {"not copying $file"
    }

}
