    and it retrieves your last command and executes it with the sudo at the beginning.
    Those are totally different issues, running the script as root is not always what you want.

    It is a terminal, and this will be implemented.
    I agree with all of your comments, but not for long.
    All of the other code will be used

    It makes it easier to use a terminal.
    This is mostly aimed for people who are tired of all those annoying error messages popping up, and beginners to Ubuntu.

    agreed, BUT! there is a but

    if your system is properly secured from the network (firewalls/nats) and OS (good passwords, sshd patched and not on weird demo keys), then adding current directory to the end of the path doesn't do much in the way of security since all other system directories are searched anyway.

    in either case, you should be using any priveledged commands under some logged super user utility (sesudo, sudo?, sudoscript, etc.)
    I am infallible, you should know that by now.

    Understood but in his example it was implied he wanted a sudo. I was demonstrating my way around when I forget to run something I need as root. I do understand the issue of changing permissions that was used in that example. I am just pointing out an alternative if and when you need to fix a missing sudo or anything you may have missed in the previous command.

    opps I misread he was not implying a sudo.

    Re: Terminal Enhancements

    I was wondering what was the security risk with adding the . to the Path.
    I know that it could be dangerous for running the script as root, but the installation doesn't run it as root.

    A malicious script could name itself "ls" and put it in the current directory. Then, the next time you want use ls, the malicious script is run instead.

    But wouldn't there be TWO ls's?
    Only one of them can run right?

    I could also add an antivirus feature, which would make this terminal the safest ever...

    As for the other issue the OP was having, it was merely a file permission problem. It appears as if the script lacked the ability to be executed. That is easily solved with:
    Code:
    chmod 744 DriverforOpenGL.sh
    I'm not having any issues. This is mostly for beginners, who are new to Ubuntu, and are used to windows.
    And I prefer;
    Code:
    chmod +x DriverforOpenGL.sh

    Yes, the first one it finds is the one it will run. But he/she can also be clever and call it sl and wait for you to slip up.
