Running an executable in Mac Terminal

Question

I just made a .c file and compiled it with gcc in the terminal on OS X 10.8.2.

My syntax was gcc -o and that was fi

Answer 1

Unix will only run commands if they are available on the system path, as you can view by the $PATH variable

echo $PATH

Executables located in directories that are not on the path cannot be run unless you specify their full location. So in your case, assuming the executable is in the current directory you are working with, then you can execute it as such

./my-exec

Where my-exec is the name of your program.
