This is an example Mime Type script to show you how to get it:

# Create Content Type Map
$ContentTypeMap = @{
	".jpg"  = "image/jpeg";
	".jpeg" = "image/jpeg";
	".gif"  = "image/gif";
	".png"  = "image/png";
	".tiff" = "image/tiff";
	".zip"  = "application/zip";
	".json" = "application/json";
	".xml"  = "application/xml";
	".rar"  = "application/x-rar-compressed";
	".gzip" = "application/x-gzip";
}
 
$File = Get-ChildItem C:\YourFilePath.json
$FileMimeType = $ContentTypeMap[$File.Extension.ToLower()];
Write-Output $FileMimeType

You can get mime types from IIS.

Posted in Windows Powershell | No Comment | 1,355 views | 23/01/2016 17:38

You can use Test-Path to test if file is exist.

But you can also use [System.IO.File]::Exists() to check it fast.

1	[System.IO.File]::Exists("Your File Path")

You can use in if block to check it on one line:

if ([System.IO.File]::Exists("C:\setup.log"))
{
Write-Output "File Exist"
}

It will also use less memory.

PowerShell’de bir değişkenin değerini dosya içeriğinden almak

Bir değişkenin değerini, dosya içeriğinden aşağıdaki gibi okuyabilirsiniz.

${C:\deneme.txt}

Değişkene aşağıdaki gibi yazdığınızda ise dosya içeriği güncellenir.

${C:\deneme.txt} = "test"

Farklı PowerShell session’larına bu şekilde variable aktarılabilir.
