Hoi there!

How do I let my program (c++) exucte a unix command (e.g. cat /proc/cpuinfo | grep "model name")? I need to collect some information about the computer it is running on, and play around with it..

I can imangine this will be very simple, as it seems to be..

cheers,
Benne

C, C++, Java, etc... can work on files...
I dont remember the C++ function that open files but it's something like fopen().
You dont need to execute a command, work directly on the file...

The C function is system() - you should be able to call it from C++ also.
