I would say that there's a big difference if a file exist or if
you don't have permission to access it. Think of the command
line, you can easily misspell a filename, or forget to use
"sudo".
This illustrates my point nicely! What does the shell do in this
case? It treats both errors the same: It prints an error
message and returns to the command line. It does not magically
try to guess the filename, find a way to get you permission, etc.
