Try putting

/usr/bin/pico /Users/colas/myfile.txt

into separate items in the argument NSArray. I find the man page ambiguous, and 
I lack direct experience, but that may be what bash expects.

I can’t guarantee that this will solve the larger problem of whether the effect 
would be to launch Terminal.app and execute the command, but it’s worth trying.
