Hi,
I want to make an application to automate some tasks under linux using C++ and GUI API(Qt, wxWidgets, GTKmm) with linux built-in applications such as ls, cp, mv, rename, ... like using popen and pclose, but I don't know how to get the return values from these commands. So I'm asking your your help for advice about ebooks, tutos, refrence, ... Anything that might help me
