-I is for information, just a command line switch, as you say, no part of
the filename.  airport -I (cap I)  make sure the space is there.
If you want to see the other switches, switch to that directory in terminal
manually run the command with the -h switch.
./airport -h
and it will show a short help listing. (can also do ./airport --help with
the double dash before help)
What error are you getting, and can you make it work from terminal?

Hmm, interesting. On my macbook it works great, fine, wonderful (snow
leopard). On my mac pro (leopard) I get an error when trying to use the -I
switch.

airport(7424) malloc: *** error for object 0x1053a0: double free
*** set a breakpoint in malloc_error_break to debug

Is that the error you get?  The main differences in my 2 machines is the OS,
leopard versus snow, and my mac pro is a wired connect no wireless hooked up
at all at the moment.

I'll see if I can find an alternate (reliable) way to get the current SSID.
