    I can,t find how I do . in C programming

    Example .

    char time
    time = system (date , 0);

    *I will take the date like I type in shell "date" = Dinsdag 26-jun-2018 11.23.56

    also command diskfree

    Example .

    int free
    free = system (diskfree work: nopostfix , 0);

    * Can somebody give a easy example to do that .

    What you are looking for is not the return value, but the output of the command. The easiest way is to redirect it into a file in T: and read it for your program.

    You should consider reading the SDK documentation. Also, there is a still valid book about all those AmigaDOS things: The Amiga Guru Book from Ralph Babel which worth to be owned just for the chapter starting quotes.

    By the way it's not a good style to depend on external commands for simple tasks if you also have a dedicated API.
    An ARexx script should of course use diskfree.
