Hi all, I'm trying to launch a windows application from terminal. I have a symlink 'dymola' to 'dymola.app'. Clicking these links in finder will open Dymola. The following command in terminal also works: > open /path/dymola Dymola can also be launched with the argument /nowindow, which I can get to work as follows: > open /path/dymola --args /nowindow Now I want to open a file x.mos which I can do as follows: > open /pathtofile/x.mos -a /path/dymola The problem is that when I now try to pass the /nowindow argument it gets passed to x.mos instead of dymola, which is causing me problems. My question: how can I pass this argument.. I already tried some things: 1) making a new link in windows containing: dymola.exe /nowindow -> I created a parallels .app file and symlink dymola-nowindow > open /path/dymola-nowindow -> LSOpenURLsWithRole() failed with error -10810 for the file /path/dymola-nowindow. 2) tried looking into dymola.app to see whether I can manually insert the argument there -> no luck Is there a way to pass arguments to winapphelper? 3) Tried making a dummy exectuable 'nowindowhelper' containing: "open /path/dymola --args /nowindow" > open ~/pathtofile/x.mos -a /path/nowindowhelper -> LSOpenURLsWithRole() failed for the application /path/nowindowhelper with error -10811 for the file /pathtofile/x.mos. The cleanest way seems to be option 2 where I could manually add the argument in one of Parallels links.
