If you wanted a command line file system, then you should have used
the "Objective-C Command Line File System" template :-)
That produces a main.m that has an example of how to do command line
arguments. As a bonus, it is set up to copy the file system's volume
icon to the resource fork of the resulting binary, so that when it
mounts you even get a nice looking volume icon.
If you look in the main.m from that template you will also see a line
that looks like:
// [options addObject:@"rdonly"]; <-- Uncomment to mount read-only.
Uncomment that and your file system is mounted read only. You'll also
want to change the part of the code that allocates your file system so
that you can pass in arguments based on your command line parsing.
Let me know if this doesn't solve your problem...
