Change process name in Linux

Question

I\'m on Linux and I am forking/execing a new process out of my C spawn application. Is it possible to also change the naming of these new child processes?

I want to

Answer 1

The below code sample would change the name of the process to "Testing".

    #include 
    #include 
    #include 

    int main (int argc, char *argv[]) {
    char* temp = (char*) malloc (20);
    strcpy(temp, "Testing");
    temp[7] = 0;
    printf("Argv[0] --> %s\n", argv[0]);
    argv[0] = temp;
    printf("Argv[0] --> %s\n", argv[0]);    
    return 0;
    }

The output of above program is:

./a.out

Argv[0] --> ./a.out

Argv[0] --> Testing

The argv[0] contains the name of the process.
