A collection of powershell scripts that I create..

powershell-samples-01.ps1

#script to list all eventlog entries with a specific text in the description

$regex_to_match=".*RoutingExtensions.*"

Get-EventLog -LogName "Application" | Where-Object {$_.Message -match $regex_to_match} | format-list -Property Source,EntryType,Message,TimeWritten


#filter eventlog entries based on date and regular expression
$regex_to_match=".*DfpLibrary.*"
$dateVal = (get-date 2013-07-01)
Get-EventLog -LogName "Application" | Where-Object {$_.Message -match $regex_to_match -and $_.TimeWritten -gt $dateVal} | format-list -Property Source,EntryType,Message,TimeWritten
