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.

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:

1
2
3
4

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

It will also use less memory.

You can simply check .NET Core status with following code:

1
2
3
4
5

# Check PSEdition
if ($PSVersionTable.PSEdition -eq "Core")
{
Write-Host "Core Edition";
}

You can check it on Nano server.

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.

Cronjob’a günlük olarak tanımlayıp, 1 hafta önceki log dosyalarının otomatik ziplenerek silinmesini sağlayabilirsiniz.

IIS’in PowerShell Management Yönetim aracına ihtiyaç duyar. Kurulu değil ise Roles’den ekleyebilirsiniz. Fakat default olarak genelde kurulu olur.

This is a query of mine, which gives you detailed information about indexes on one query:

SELECT SO.NAME AS TableName, PS.object_id AS ObjectId, SI.NAME AS IndexName, PS.index_id AS IndexId, SUM(PS.RESERVED_PAGE_COUNT*8) TotalStorage, SUM(PS.USED_PAGE_COUNT*8) UsedStorage, SUM((PS.RESERVED_PAGE_COUNT - PS.USED_PAGE_COUNT)*8) FreeStorage,
SUM(CASE WHEN PS.INDEX_ID IN (0,1) THEN PS.ROW_COUNT ELSE 0 END) AS ROW_COUNT,
MAX(round(Avg_Fragmentation_In_Percent, 2)) AS 'AvgFragmentationInPercent',
MAX(fragment_count) AS FragmentCount,
MAX(ips.page_count) AS PageCount,
MAX(ius.user_scans) AS UserScans, MAX(ius.user_seeks) AS UserSeeks, MAX(ius.user_lookups) AS UserLookups
FROM
SYS.DM_DB_PARTITION_STATS PS
INNER JOIN sys.dm_db_index_physical_stats(5,NULL,NULL,NULL,'LIMITED') AS ips
ON ps.object_id = ips.object_id AND
       ps.index_id = ips.index_id
INNER JOIN SYS.OBJECTS SO ON SO.OBJECT_ID = PS.OBJECT_ID
LEFT JOIN SYS.INDEXES SI ON SI.OBJECT_ID = PS.OBJECT_ID
AND SI.INDEX_ID = PS.INDEX_ID
LEFT OUTER JOIN sys.dm_db_index_usage_stats ius ON ius.database_id = 5 AND ps.object_id = ius.object_id AND ps.index_id = ius.index_id
WHERE
SO.IS_MS_SHIPPED = 0
GROUP BY so.name, ps.object_id, si.name, ps.index_id
ORDER BY UserLookups DESC

You can also add Schema column if you have different db schemeas.

Check following query to improve your database performance:

EXEC sys.sp_configure N'show advanced options', N'1'  RECONFIGURE WITH OVERRIDE
GO
EXEC sys.sp_configure N'max server memory (MB)', N'11000'
GO
RECONFIGURE WITH OVERRIDE
GO
EXEC sys.sp_configure N'show advanced options', N'0'  RECONFIGURE WITH OVERRIDE
GO
EXEC sys.sp_configure N'show advanced options', N'1'  RECONFIGURE WITH OVERRIDE
GO
EXEC sys.sp_configure N'max degree of parallelism', N'1'
GO
EXEC sys.sp_configure N'max server memory (MB)', N'11000'
GO
EXEC sys.sp_configure N'optimize for ad hoc workloads', N'1'
GO
RECONFIGURE WITH OVERRIDE
GO
EXEC sys.sp_configure N'show advanced options', N'0'  RECONFIGURE WITH OVERRIDE
GO

This is a note for myself. So you should edit config to meet your requirements.
