The Robot Lives

Courtesy of the long list of things you probably shouldn’t do but will anyway heres how one goes about implementing mutex locking between multiple powershell scripts.

<#
1. Instantiate Mutex Object using new-object syntax
2. Use the same "DesiredMutexName" across scripts.  Or move mutex logic into a shared script included by each script desiring access to these mutexes.  (. Path\ScriptWithMutexLocks.ps1)
#>
$mutex = new-object -TypeName System.Threading.Mutex -ArgumentList $false, "YourDesiredMutexName";

# 3. Lock Access to critical sections in each script
$result = $mutex.WaitOne();
<#
Critical Section
#>

#4 Release
$mutex.ReleaseMutex();
<#
Script Specific / Non viotile section
#>

. . . Enjoy
