But if I type the following this is what I see:

o-shell>exit exit exit
exit was entered
There are 0 arguments
Command is exit
Segmentation fault (core dumped)


There should be two arguments (two exits after the command exit) counted. So the args pointer shouldn't be NULL, unless the strtok code that I entered is wrong...which is what I'm looking for --- the error.
