Sorry, I did not use the converter, but I would try explicitly specify the name of the output file:
btw, you can make you paths shorter by cd ~/Documents/Standalone_Converter
Thanks for the suggestion. Itried that to start with but unfortunately the script won't run. It seems to only work when I specify a folder location and not new file name.
OK, I was wrong. Looking at manual now. Looks like you need .sh extension after fmdbconverter -> fmdbconverter.sh
any chance that the file wasn't properly closed? What OS version?
-> Drag the .fp7 file on FileMaker 13 (or 12) icon and see what happens
