Hi,
I'm new to this forum and a unix newbee. You'll probably see lots of posts from me comming up for the next few months.

I had to install unix because I'm doing C programming for unix.
I started with something simple, a hello world C program, which I saved as hello.c

I then compiled as
gcc hello.c -o hello

This makes an executable binary file in the same dir.
But how do I run it? If I just type 'hello' and press enter it says 'command not found'. I also tried running it through the GNOME interface but nothing happens.

I'm using Redhat 7.2 with GNOME.

For security reasons the current directory is not normally in your PATH on most Linux setups. To run a program in the current directory, do this:

./hello

Thanks mhearn. That did the trick.
