Ich habe einen Ordner voller Protokolldateien auf einem Windows-Rechner (Windows Server 2008 R2, oder ich könnte sie auf Win10 kopieren) und möchte sie nach Datum komprimieren. Ich würde das gerne mit nativen Mitteln machen (z. B. CMD/BAT, Powershell), ohne etwas installieren zu müssen. Vielleicht sind meine Suchbegriffe zu allgemein, aber ich habe Probleme, den Zauberspruch dafür zu finden.
Es sollte mit gemischten Dateitypen funktionieren und ich sollte auswählen können, welches Datum verwendet werden soll.
Hier ein Beispielsatz (US-Datumsformat):
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
Könnte werden:
190102.zip
log1.log
log2.txt
190103.zip
log3.log
Oder:
190101.zip
log1.log
190102.zip
log2.txt
log3.log
Antwort1
Normalerweise machen die Leute das nicht, wie ich oben schon sagte, aber dieses Mal werde ich es tun, damit Sie verstehen, was ich damit meine, wie man vorgeht, und daraus lernen.
Wie Sie aus dem Folgenden ersehen werden, würde sich diese Art von Material nie an einem Ort befinden, es sei denn, jemand hat es bereits aufgeschrieben und veröffentlicht. Alle werden möglicherweise auch unterschiedliche Ansätze haben. Sie müssten also einen finden, den Sie akzeptieren und mit dem Sie sich langfristig befassen möchten.
Abzweigung von meinen vorherigen Kommentaren.

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
