I just purchased Red Hat Linux 8 Bible by Chris Negus, used. I loaded
Linux 8.0 with the purpose of learning C via Kernigan and Ritchie,
Linux, and Nasm. I didn't install any GUI, I'm going to work in the
shell.

I installed "developer tools" , and wrote the Hello World program
verbatim from K&R in my home directory. When I type "gcc hello.c", no
error messages appear, and a.out appears in the current directory.

But, when I try to run Hello, world by typing "a.out", the shell
returns:

-bash no command a.out found

or something very close to that, I'm not sitting at that computer right
now.
I tried changing the name of a.out, and it still doesn't work.

Do you have your local directory (.) in your search path? Also what are
the permissions on a.out? Do a chmod +x a.out and see if that fixes your
problem.

When executing a program in the local directory which in not in the $PATH,
as noted above, you need to use:

./a.out

That is, precede the name of the executable with "./", which tells Linux
where to find the executable.

This is a security feature, which makes it more difficult (though not
impossible) to execute malicious programs that you may have downloaded.

BTW, as others will likely note, RH 8.0 has long been a dead product. The RH
releases have been superceded by Fedora which is now up to version 7.
