[英]Deleting files inside the folder from specific date using powershell
My folder structure looks like this:我的文件夹结构如下所示:
AK_Data |--->2020-01-22-------|----->a.txt
| |----->b.txt
| |------>c.tf.err
|
|--->2021-01-15-------|----->d.txt
| |----->b.txt
| |------>x.tf.err
|
|--->2022-01-08-------|----->dv.txt
| |----->pq.bat
|
|--->2022-05-08-------|----->xyz.pdf
AK_Data
is the first folder which consists of multiple subfolders
like (2020-01-22,2021-01-15.....)
and these each subfolders contains 1000
of their different format files. AK_Data
是第一个包含多个subfolders
,例如(2020-01-22,2021-01-15.....)
,每个子文件夹包含1000
不同格式的文件。
I need to go into each folder and delete all the files except those files having ".tf.err"
in their names.我需要进入每个文件夹并删除所有文件,但名称中
".tf.err"
的文件除外。 I have used $specificdate='2022-01-01'
means the files of the folder less than 2022-01-01
only needs to be deleted.我使用
$specificdate='2022-01-01'
意味着只需要删除小于2022-01-01
的文件夹的文件。 So my expected output is:所以我的预期输出是:
AK_Data |--->2020-01-22-------|------>c.tf.err
|
|
|
|--->2021-01-15-------|------>x.tf.err
|
|
|
|--->2022-01-08-------|----->dv.txt (this folder will be untouched since>2022-01-01)
| |----->pq.bat
|
|--->2022-05-08-------|----->xyz.pdf (this folder will be untouched since>2022-01-01)
I only need to delete the files inside the folder, not the folder.我只需要删除文件夹内的文件,而不是文件夹。
The powershell I used for this is:我用于此的 powershell 是:
cls
$specificdate='2022-01-01'
$destination = 'Y:\Data\Retail\ABC\Development\ak\AK_Data'
$files = Get-ChildItem $destination
$exte='\.(bz2)|(.bat)|(.err)|(~)'
foreach ($f in $files){
$outfile = $f.FullName -notmatch $exte
if ($outfile){
if ($f.Name -lt $specificdate){
$allfiles=Get-ChildItem $f.FullName -Exclude *.tf.err* -Name | remove-item -whatif
}
}
}
It is not deleting the files.它不是删除文件。
I would do this by first iterating the source folder path for directories with a name that can be converted to a datetime less than the datetime in variabe $specificDate
.我会通过首先迭代目录的源文件夹路径来做到这一点,该目录的名称可以转换为小于变量
$specificDate
中的日期时间的日期时间。
Then use Get-ChildItem
again inside these folders to find and remove files that do not have .tf.err
in their name:然后在这些文件夹中再次使用
Get-ChildItem
来查找并删除名称中没有.tf.err
的文件:
$specificdate = [datetime]::ParseExact('2022-01-01','yyyy-MM-dd', $null)
$sourceFolder = 'Y:\Data\Retail\ABC\Development\ak\AK_Data\*'
Get-ChildItem -Path $sourceFolder -Directory |
Where-Object { [datetime]::ParseExact($_.Name,'yyyy-MM-dd', $null) -lt $specificdate } |
ForEach-Object {
Write-Host "Removing files from folder $($_.Name).."
Get-ChildItem -Path $_.FullName -File |
Where-Object { $_.Name -notlike '*.tf.err*' } |
Remove-Item -WhatIf
}
Again here, I added the -WhatIf
switch so you can first see what WOULD happen.再次在这里,我添加了
-WhatIf
开关,这样您就可以首先看到会发生什么。 If you're OK with that, remove -WhatIf
and run the code again to actually delete the files如果您同意,请删除
-WhatIf
并再次运行代码以实际删除文件
