Check the Parameters Expected for a PowerShell Script

Q. How can I quickly check in PowerShell what parameters a script expects?

A. One way is to simply open the PowerShell script and examine the code, but there's an even easier way:

help .This will output the parameters and the types expected. An example is shown below which demonstrates the script expects a string value to be passed.PS C:> help .checkos.ps1 -Fullcheckos.ps1 [[-computername] ]
