Cannot mark scripts as executable

[xmanmonk]

I fully understand that this may be an issue with the underlying OS (Android), but in the spirit of making sure everything works as well as in linux, I have written some shell scripts. I'm running debian. I am unable to get them to run because I cannot mark them as executable nor can I pass them as -c parameters to bash. The files are on the phone's storage (i.e. not on the sd card). Is there a way to make this work?

I think Android mounts external storage as R/O. Not sure though.
