У меня есть папка, полная файлов журналов на машине Windows (Windows Server 2008 R2, или я могу скопировать их на Win10), и я хочу сжать их по дате. Я бы с удовольствием сделал это с помощью собственных средств (например, CMD/BAT, Powershell), не устанавливая ничего. Возможно, мои поисковые запросы слишком общие, но у меня возникли проблемы с поиском магического заклинания, которое это сделает.
Он должен уметь работать со смешанными типами файлов, и я должен иметь возможность выбирать, какую дату он хочет использовать.
Итак, в качестве примера (формат даты в США):
log1.log Created 1/1/19 12:59p Last Modified 1/2/19 1:09a
log2.txt Created 1/2/19 8:00a Last Modified 1/2/19 8:00a
log3.log Created 1/2/19 12:59p Last Modified 1/3/19 1:09a
Мог стать:
190102.zip
log1.log
log2.txt
190103.zip
log3.log
Или:
190101.zip
log1.log
190102.zip
log2.txt
log3.log

Обычно люди этого не делают, как я уже сказал выше, но в этот раз я сделаю это, просто чтобы вы поняли, что я имею в виду, говоря о том, как к этому подходить, и извлекли из этого урок.
Как вы определите из нижеизложенного, такого рода вещи никогда не будут находиться в одном месте, если только кто-то уже не написал и не опубликовал их. У всех будут потенциально разные подходы. Поэтому вам придется найти тот, который вы планируете принять и с которым вы будете иметь дело в долгосрочной перспективе.
Продолжая мои предыдущие комментарии.

What you are after for full understanding is a multi-staged effort, using:
Get-ChildItem
PowerShell Date Formatting
Compress-Archive or .Net (depending on what PowerShell versio you are using)
Example:
if ($PSVersionTable.PSVersion.Major -ge 5)...
{
Compress-Archive -Path $FileSource -DestinationPath $ZipDestination...
}
else
{
# If PowerShell version is below 5x
Add-Type -assembly "system.io.compression.filesystem"
[io.compression.zipfile]::CreateFromDirectory($FileSource, $ZipDestination) ...
}
#>
# Define file source and zip destation paths
$FileSource = 'F:\Temp'
$ZipDestination = 'F:\Temp\Archive'
# Get the first file and check for all properties to see what can be used
(Get-ChildItem -Path $FileSource -File)[0] |
Select-Object -Property '*' | Format-List -Force
