  #290108

  i cannot for the life of me pinpoint my error here.

  this should be fairly simple: find matching files, and print em out before i explicitly delete them.

  i'm trying to test each file in a folder to match certain criteria to determine whether i want to delete it or not.

  eventually it will be four items total,including "older than x days, but i cannot even get the first item to filter and prove it was found.

  i'm trying to find something that matches a database name between underscores, and starts with "FULL_" and also the "right" extension.

  As far as i know, it's never even entering /testing my if statement.

  i thought maybe the underscores were part of the problem with a -LIKE statement, but even removing them doesn't get me to return anything inside the write-host commands.

  I've tried -like, startswith, and lots of other variations, but i'm obviously stuck on something super basic that my programming skillset assumes or takes for granted.

  can anyone see an obvious mistake here?

  #folder contains the following files for example:

  #FULL_(local)_CommonSecurity_20140407_141304.sqb

  #FULL_(local)_dbWarden_20140407_141304.sqb

  #FULL_(local)_master_20140407_122503.sqb

  #FULL_(local)_model_20140407_122505.sqb

  #FULL_(local)_msdb_20140407_122505.sqb

  #FULL_(local)_ReportServerTempDB_20140407_141305.sqb

  #variable definitions

  $dbname="CommonSecurity";

  $Full_LOG_or_DIFF = "FULL";

  $extension = ".sqb";

  $limit = (Get-Date).AddDays(-7)

  $fl = Get-ChildItem -path "C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Backup" ;

  foreach($item in $fl)

  {

  Write-Host $item.Name;

  if ( $item.Name -like ".sqb")

  {

  Write-Host $item.Name;

  Write-Host $item.FullName;

  }

  #if ( $item.Name -like "_${dbName}_" -and $item.Name.StartsWith("${Full_LOG_or_DIFF}_") -and $item.Name -like $extension -and $_.CreationTime -lt $limit)

  if ( $item.Name -like $extension )

  {

  Remove-Item $item.FullName -WhatIf;

  }

  }

  Just a small change.

  from if ( $item.Name -like ".sqb")

  to if ( $item.Name -like "*.sqb")

  and if ( $item.Name -like "*.$extension")

  Also, if you want to cut down the files returned to $fl from Get-ChildItem add the -Filter option.

  $fl = Get-ChildItem -path "C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Backup" -Filter "$Full_LOG_or_DIFF*$extension"
