A key feature of CMD is its capability to run batch files. A batch file is a script file containing a series of commands that are executed sequentially, this way users can automate repetitive tasks, such as backing up files, modifying system settings, or installing applications. C...
One advantage of Windows PowerShell Workflows is the ability to perform a set of commands in parallel instead of sequentially as with a typical script. This is particularly useful in runbooks since they may perform multiple actions that take a significant time to complete. For example, a runbook...
Work consists of significant waiting - A script that spends time waiting for I/O or remote call results. Running in parallel usually completes quicker than if run sequentially. PowerShell (Measure-Command{1..1000|ForEach{Start-ThreadJob{Write-Output"Hello$using:_"} } |Receive-Job-Wait}).Tot...
The answer is speed. For instance, you might need to perform a task on several machines, but you don't have enough time to sequentially work through the list of machines. Alternatively, there might be long stretches of time during which your code waits for something to happen; performing ...
Because each script block in the ForEach-Object example above takes 1 second to run, running all five in parallel takes only one second instead of 5 seconds when run sequentially. Since the script blocks are run in parallel for each of the 1-5 piped input integers, the order of execution...

For multiple debuggable child jobs, each job execution will be halted and the debugger will step to each job execution point sequentially. When a job is debugged its output data is written to host and the executing job script will break into the host debugger, in step mode, at the next ...
commands executed on it, a new file copied and service restarted, to fix them so I created a quick VBScript to connect to each machine and perform the fix actions. The only bad part about this script was that it took days to run against the machines, processing each one sequentially in ...
consider disabling parallel execution by temporarily removing the-ParallelorAsyncswitches. You can also force all activities to execute sequentially by setting thePSYForceSequentialPowerSync variable to$true. If the problem only occurs during parallel execution, theWaitDebuggerswitch will force each remote ...
For an experienced programmer to learn a new language can be a journey quite like Alice's in wonderland. Paradoxes, unexpected twists, blind tangents, bafflements and nice surprises. Michael comes to the rescue of anyone learning PowerShell with an expla
