Hi, noobie here.

I'm trying to gcc a helloworld in RedHat Linux 6.1, so I

gcc helloworld.c

which comiles successfully, and I end up with a.out.

But I can't get it to run, despite entering

a.out <Enter>

Can anyone help me out here? I'm following a book 'Teach Yourself Linux' by Steve Oualline and Eric Foster Johnson. The book's examples don't look like what comes up on screen.

sincerely,
cow.
