    I am trying to run a piece of code that calls the cksum and pass its output in to a variable in my code. I realise I can channel it to a text file and then open it and read it in, but this seems very dodgy and so I am hoping for a better way to do it. Please any ideas?

    Code:
    system("cksum /path/to/file")
    :confused:

    For those of you the come here looking for an answer to this question, I found the solution. You need to use popen().
    just lookup examples and documentation for more detail :)
