[Majd Participant Topics: 15 Replies: 13 Points: 83Rank: Member]

I do not understand what is the difference between

PowerShell

Invoke-Expression & something

1	Invoke-Expression & something

and

PowerShell

Start-Process something

1	Start-Process something

 

Can one please explain it with an example. And is call operator & from Powershell or Docs.

Thanks alot.

The call (&) and Invoke-Expression are used to execute something, basically run it. See the Call Operator here:

https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_operators?view=powershell-7.1

Start-Process provides a more parameter based approach with functionality such as waiting for completion to get exit codes rather than just starting a process. There are examples included in the documentation.
