I've noticed subtle differences in execing a batch file on MS Windows with or without prepending the call with the command interpreter, cmd.exe. Here's an example:
(Eigene) 1 % cd c:/iskv/portal_1024 couldn't change working directory to "c:/iskv/portal_1024": no such file or directory (portal_01024) 2 % cd c:/iskv/portal_01024 (portal_01024) 3 % glob * config cti dist help resource resource_cti start_portal.bat (portal_01024) 4 % exec -- start_portal.bat Unable to access jarfile c:\iskv\21c_winbk_\bin\csvstart.jar Das System kann den angegebenen Pfad nicht finden. (portal_01024) 5 % exec -- cmd.exe /c start_portal.bat (portal_01024) 6 % exec -- cmd.exe /c start_portal.bat & 4660 (portal_01024) 7 % exec -- [auto_execok start_portal.bat] Unable to access jarfile c:\iskv\21c_winbk_\bin\csvstart.jar Das System kann den angegebenen Pfad nicht finden. (portal_01024) 8 %
Don't know what's going on yet.
