Compiling a C program in Redhat 8.0

[Yohhan]

Trying to compile a C program in linux (redhat 8.0). I type:

$ cc helloworld.c

and it compiles and puts "a.out" in the same directory. However, when I try to run the program by typing:

$ a.out

I get the error message:
-bash: a.out: command not found

Any ideas why that would happen? When I list the directory, "a.out" is highlighted in green, which I'm pretty sure means it's an executable. Why does it give me the error?

Thanks ahead.

try ./a.out

basically its not in your executable path, so the ./ makes it execute in the current directory

Oh okay. How can I put it in my executable path?

 

[Whitecloak]

are you certain that a.out has execute permissions?

move it to a directory in your path.

... or you can change your $PATH environment variable to include '.' ... This is somewhat frowned upon (for security reasons), but if you must do it, put '.' at the very end of the list....

Get used to using bash's tab completion. Type ./a<tab> and it'll finish typing .out for you.
