Weekend Project: Process Explorer Auto Install

I was bored this weekend and decided to try my hand at making a PowerShell script to automate the install of Sysinternals Process Explorer. It’s pretty rough product of about 3 hours of work. I’ll make improvements in the future as I get time. In any case, it’s available below.

#### Downloads Process explorer from download.sysinternals.com,
#### unzips it into Program Files and then cleans up.

Shell Script: Splunk Syslog Server Update script

Here is a set of upgrade scripts I’ve created to automatically upgrade Splunk Syslog Server on Linux. This is primarily written with ubuntu server in mind, specifically 12.04 LTS, though it’s easily editable for other distributions. You can download the files below (they are automatically zipped with the latest version.

wget -q --secure-protocol="auto" -O "splunkget.sh" "https://raw.github.com/Smokex365/Splunk_Upgrade_Scripts/master/splunkget.sh"
chmod u+x splunkget.sh

PowerShell: Empty Recycle Bin

Here is a quick PowerShell script I found recently to clear the Windows Recycle Bin. This can be really useful if you want to automatically empty the Recycle Bin through something like the Task Scheduler. This code comes from the TechNet Script Center, courtesy of Windows Engineer and PowerShell Blogger Rich Prescott.

$Shell = New-Object -ComObject Shell.Application
$RecBin = $Shell.Namespace(0xA) 
$RecBin.Items() | %{Remove-Item $_.Path -Recurse -Confirm:$false}

This script allows you to view the contents of the recycle bin in your profile. The first line creates a ComObject and then the second line grabs the Recycling Bin special folder. It then enumerates the items contained in that special folder and removes each of them. The Remove-Item cmdlet includes a switch to turn off confirmation for the removal of the files. It can be removed if you would like to be prompted for each file.

Works on:

Windows Server 2012 and Up Yes Windows 10 and Up Yes
Windows Server 2008 R2 Yes Windows 8 Yes
Windows Server 2008 Yes Windows 7 Yes
Windows Server 2003 No Windows Vista Yes
Windows XP Yes
Windows 2000 No

PowerShell : Uptime scripts

I wanted a quick way to determine uptime for my servers and other windows computers and so started searching for solutions. After some time I finally found some good information but it wasn’t entirely user friendly. After another 2 hours of researching and trying to get it right, I came up with these scripts for displaying your computer’s uptime. The PowerShell scripts aren’t mine (you’ll find links to the originals below) but the batch files are. Pretty simple but a nice time saver.
