Functionality

• The script is executable from the command line
  • for Windows by use of the pwsh.exe PowerShell interpreter like this:
    • pwsh.exe -f ./Start-JobSchedulerOrder.ps1 -JobChain /bjb/shell_chain -Order sample_order
  • for Linux and MacOS by directly calling the script and by implictly using the shebang (#!/usr/bin/pwsh) to reference the interpreter like this:
    • ./Start-JobSchedulerOrder.ps1 -JobChain /bjb/shell_chain -Order sample_order
• Use of JobScheduler PowerShelll CLI
