Delete Files and Folders Older Than X Days
Often times admin have to creates tasks like removing log files or some other files on a regular schedule. Here is an automated way of removing files / folders older than X days. Create a Batch file or Powershell script and add it to scheduled task. Batch File:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
@echo off :: set folder path set dump_path=c:\shares\dump :: set min age of files and folders to delete set max_days=7 :: remove files from %dump_path% forfiles -p %dump_path% -m *.* -d -%max_days% -c "cmd /c del /q @path" :: remove sub directories from %dump_path% forfiles -p %dump_path% -d -%max_days% -c "cmd /c IF @isdir == TRUE rd /S /Q @path" |
Powershell:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
# set folder path $dump_path = "C:\shares\dump" # set min age of files $max_days = "-7" # get the current date $curr_date = Get-Date # determine how far back we go based on current date $del_date = $curr_date.AddDays($max_days) # delete the files Get-ChildItem $dump_path -Recurse | Where-Object { $_.LastWriteTime -lt $del_date } | Remove-Item |
Remove disabled users from Distribution Lists & Security Groups in Active Directory
One of my clients had several disabled users showing up in distribution lists and security groups and this was creating unnecessary noise in email, alerts, etc. I highly encourage all administrators to keep their AD neat and tidy. The following PowerShell script searches for disabled users in Groups and Distribution Groups and removes them:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
# This script removes all disabled users from all security and distribution groups in the specified "searchOU" Import-Module ActiveDirectory $searchOU = "OU=Groups,DC=domain,DC=local" $adgroup = Get-ADGroup -Filter 'GroupCategory -eq "Security" -or GroupCategory -eq "Distribution"' -SearchBase $searchOU $adgroup | ForEach-Object{ $group = $_ Get-ADGroupMember -Identity $group -Recursive | %{Get-ADUser -Identity $_.distinguishedName -Properties Enabled | ?{$_.Enabled -eq $false}} | ForEach-Object{ $user = $_ $uname = $user.Name $gname = $group.Name Write-Host "Removing $uname from $gname" -Foreground Yellow Remove-ADGroupMember -Identity $group -Member $user -Confirm:$false } } |
