Easy question: what is the easiest way to execute an external program (with parameters) from C++ (using g++ and Linux)? Is there an easier way rather than doing fork/exec and waiting? I just need to execute the command and wait for it to finish.
Kind of depends on how much you want to interact with the program.
If not at all, you can easily just use system("....");
If you want some I/O then you can use popen();
And if even that is not enough, you will end up will fork()
, exec()
, wait()
, dup()
and other functions from this family.
