A few weeks ago, I began setting up a couple SRCDS servers to play TF2 with friends. One of the first issues I encountered was that Steam never fixed auto-update. I made a little tool I call FusiblePlug (in keeping with the steam-related names for things) that solved this problem.
It’s early; its basic; its bound to have flaws, but it works for me. I wanted to share it with the forum as it’s an cool example of something you can do with PowerShell. It’s gone through a few iterations and below is the latest.
What it does:
- Checks to make sure srcds.exe is running
- Starts srcds.exe with your defined parameters if it’s not running
- Shuts down the server and updates if an update command is logged
- Randomize the start map (if you so wish)
- Produce basic logs so an admin can see when it ran and what actions were performed (if you so wish)

# This script handles checking to see if srcds.exe
# is running, starts it if not, and checks to see if
# game files are out of date by reading the log file
# for a request to update from Valve. After updating,
# srcds.exe is restarted. Use task scheduler to run
# This script at an interval you define.
#
# Recommended: 10 minutes.

Please feel free to critique with syntax or overall usage. I’m not a programmer, but I do dabble in scripting when my work needs something. I’m finding myself liking PowerShell the more I use it.
