PowerShell script to remove old IIS log files

Application logs can stop your machine if you do not control their size. By default, webserver IIS doesn't clean IIS logs and stores them in c:\inetpub\logs. If your server is high loaded, logs of IIS can get critical size in 2-3 weeks.
In this script I remove all the IIS log files older than 10 day. It's value is hardcoded, but you can change it.

#Get log files from all subdirectories 
$iislogs = Get-ChildItem C:\inetpub\logs\LogFiles –Recurse 
#select only files which are older than 10 days 
$iislogsrem = $iislogs | where {$_.LastWriteTime -le (Get-Date).AddDays(-10) -and !$_.PSIsContainer} 
#removing files 
$iislogsrem | Remove-Item

#Get log files from all subdirectories

$iislogs = Get-ChildItem C:\inetpub\logs\LogFiles –Recurse

#select only files which are older than 10 days

$iislogsrem = $iislogs | where {$_.LastWriteTime -le (Get-Date).AddDays(-10) -and !$_.PSIsContainer}

#removing files

$iislogsrem | Remove-Item

Or you can combine it to one expression:

$iislogs = Get-ChildItem C:\inetpub\logs\LogFiles –Recurse | where {$_.LastWriteTime -le (Get-Date).AddDays(-10) -and !$_.PSIsContainer} | Remove-Item

1	$iislogs = Get-ChildItem C:\inetpub\logs\LogFiles –Recurse \| where {$_.LastWriteTime -le (Get-Date).AddDays(-10) -and !$_.PSIsContainer} \| Remove-Item

Of course, you can easily modify this script to remove any logs or other files.
