Windows PowerShell is a mix of command-line shell and scripting language. You find more Information about PowerShell here and here. With the free COM library ActiveXPosh.dll from SAPIEN you can also use PowerShell inside ABAP. In this blog I will show how to do that.
Here an example how to get all services and its state.
"-Begin----------------------------------------------------------------- Program zPSTest. "-Constants----------------------------------------------------------- Constants: OUTPUT_CONSOLE Type i Value 0, OUTPUT_WINDOW Type i Value 1, OUTPUT_BUFFER Type i Value 2 . "-Variables----------------------------------------------------------- Data: PS Type OLE2_OBJECT, Result Type i, strResult Type String, tabResult Type Table Of String, cmd Type String .

Call Method Of PS 'Init' = Result Exporting #1 = 0. If Result 0. Free Object PS. Exit. EndIf. Call Method Of PS 'IsPowerShellInstalled' = Result. If Result = 0. Free Object PS. Exit. EndIf. Set Property Of PS 'OutputMode' = OUTPUT_BUFFER. cmd = `Get-WmiObject -class Win32_Service | `. cmd = cmd && `Format-Table -property Name,State`. Call Method Of PS 'Execute' Exporting #1 = cmd. Call Method Of PS 'OutputString' = strResult. Split strResult At cl_abap_char_utilities=>cr_lf Into Table tabResult. Loop At tabResult Into strResult. Write: / strResult. EndLoop. Free Object PS. "-End-------------------------------------------------------------------You can use with PowerShell all dotNET and Windows standard libraries. On this way you can extend your possibilities.
Here a class to use PowerShell in ABAP easily:
