Hi,

You don't execute a .c file directly in a terminal. You compile it with a c-compiler like gcc or clang to an executable format and execute that.

The program you show would create a number of child processes. But if you don't know what the fork() statement does, I would advise you to get a nice beginners book about C and start off with something simple like

Code:

#include <stdio.h>

int main()
{
    printf("Hello, World\n");
    return 0;
}

Cheers,

Hi,

There are already a lot of posts on this site that could tell you how, also reading the man-pages could tell you probably how.
But basic command to compile is:

gcc <inputfiles> -o <executable file>

Example: gcc test.c -o test

To execute:

./test

Cheers,
