I am using VI editor at work to try to compile my programs for school in C. When I compile I get the file a.out. When I do this on the school's site I am able to just type a.out in the command line and it runs. They are using AIX (whatever that means). I cannot do that here. It keeps saying no such file. I am using Linux, that is about all I know. Can anyone point me in the direction to be able to run my file after compiling it. I hope I gave you all the info. Unfortunately I am not that familiar with Unix. Thanks. :confused:
