Shell Programming and Scripting
Checking if file exists using a NOT operator and shell variable

Concerning your first problem, you need to move the ! in front of "-e". Otherwise you're just negating the command line argument.
About your second problem: Why don't you call "exit" with the respective error code? OK, I wasn't fast enough

allegro_exit
allegro_exit(3alleg4) Allegro manual allegro_exit(3alleg4) NAME
allegro_exit - Closes down the Allegro system. SYNOPSIS
#include <allegro.h> void allegro_exit(); DESCRIPTION
Closes down the Allegro system. This includes returning the system to text mode and removing whatever mouse, keyboard, and timer routines have been installed. You don't normally need to bother making an explicit call to this function, because allegro_init() installs it as an atexit() routine so it will be called automatically when your program exits. Note that after you call this function, other functions like destroy_bitmap() will most likely crash. This is a problem for C++ global destructors, which usually get called after atexit(), so don't put Allegro calls in them. You can write the destructor code in another method which you can manually call before your program exits, avoiding this problem. SEE ALSO
