#include <iostream>
#include <cstdlib>

using namespace std;

int main()
{

        system( "echo Date: `date`" );
        system( "echo Uptime: `uptime`" );
        system( "echo Name: `uname -n`" );
        system( "echo Kernel: `uname -r`" );
}

I run this program with the command ./sysinfo
But I want to be able to add flags for instance ./sysinfo -d prints only the date line, can someone tell me how to make that possible? And also I found a line in bash that displays the hdd space.

(Toggle Plain Text)

 df | awk '{ sum+=\$2/1024^2 }; END { printf (\"%dGb\", sum 
             )}

Can someone tell me how to turn that into C++ code?
