    terminal command with password
    Hi, I'm new the development in Mac. I need to call a command line as following using C++ with system() function:
    "sudo rm /private/var/db/.AccessibilityAPIEnabled"
    I'm expecting this line being executed in background, however in my C++ console application, it would prompt for a password, I need to eliminate this step. Is there something like "sudo rm /private/var/db/.AccessibilityAPIEnabled -p MyPassword" in Mac?
    Thanks a lot!

    To run a SUDO command without using your password, you can configure SUDO to allow a particular (or all) commands to be run without the password.

    So do
    sudo visudo
    which will take you to a file that controls how SUDO functions. Towards the bottom you'll see something like #
    %wheel ALL=(ALL) NOPASSWD: ALL
    so you could add something like the following
    <username> ALL=(ALL) NOPASSWD: rm
    and it will allow you to do the rm as SUDO without requiring a password.

    Note that this means ANY rm you do will no longer require a password, so it might be dangerous..

    thanks Raz0rEdge, i tried it, it works. however this might not be a perfect solution to my problem. i'm using a C++ app to call a command as such: "sudo rm /private/var/db/.AccessibilityAPIEnabled". i'm looking for a way to in-build the admin password into the command. i agree with you that adding "<username> ALL=(ALL) NOPASSWD: rm" would be dangerous, therefore i think this way is not a good approach to my problem. is there a way that i can skip the password prompt only in my app?
