I have a path in a string,
"C:\temp\mybackup.zip"
I would like insert a timestamp in that script, for example,
"C:\temp\mybackup 2009-12-23.zip"
Is there an easy way to do this in PowerShell?
This question is related to
powershell
Use:
$filenameFormat = "mybackup.zip" + " " + (Get-Date -Format "yyyy-MM-dd")
Rename-Item -Path "C:\temp\mybackup.zip" -NewName $filenameFormat
Here's some PowerShell code that should work. You can combine most of this into fewer lines, but I wanted to keep it clear and readable.
[string]$filePath = "C:\tempFile.zip";
[string]$directory = [System.IO.Path]::GetDirectoryName($filePath);
[string]$strippedFileName = [System.IO.Path]::GetFileNameWithoutExtension($filePath);
[string]$extension = [System.IO.Path]::GetExtension($filePath);
[string]$newFileName = $strippedFileName + [DateTime]::Now.ToString("yyyyMMdd-HHmmss") + $extension;
[string]$newFilePath = [System.IO.Path]::Combine($directory, $newFileName);
Move-Item -LiteralPath $filePath -Destination $newFilePath;
I needed to export our security log and wanted the date and time in Coordinated Universal Time. This proved to be a challenge to figure out, but so simple to execute:
wevtutil export-log security c:\users\%username%\SECURITYEVENTLOG-%computername%-$(((get-date).ToUniversalTime()).ToString("yyyyMMddTHHmmssZ")).evtx
The magic code is just this part:
$(((get-date).ToUniversalTime()).ToString("yyyyMMddTHHmmssZ"))
Thanks for the above script. One little modification to add in the file ending correctly. Try this ...
$filenameFormat = "MyFileName" + " " + (Get-Date -Format "yyyy-MM-dd") **+ ".txt"**
Rename-Item -Path "C:\temp\MyFileName.txt" -NewName $filenameFormat
