    Bash - Returning String From Functions


    ...how do I do it. I've read every tutorial i could find and all I found was some back asswards way of to 'pass-by-reference' and changing the actual variable sent to the function.

    Basically all I want to do is this, except using bash scripting
    Code:
    using namespace std;          //just for you code nazi's - you know who you are
    string createSomeText()
    {
             string x  = "Foo Bar"
             return x;
    }
    
    int main()
    {
          string text = createSomeText();
          return 0;
    }

    Hi.

    Yes, you need to get 2 features together, the first is the function itself, which you apparently know about.

    The other feature is:
    For purposes of command substitution, a command may be an external system command, an internal scripting builtin, or even a script function.

    -- the description of which you can find at: http://www.tldp.org/LDP/abs/html/commandsub.html
    The Advanced Bash-Scripting Guide, noted above, is a good document to look over -- it's long, but well-worth your time ... cheers, drl
