command-not-found

[williamstein]

Since our images are so minimal, it would be very useful for them to all support ubuntu command-not-found. Here's how that would work:

sudo apt-get install command-not-found
sudo apt-get update

then have to put this in some bashrc location:

command_not_found_handle () 
{ 
    if [ -x /usr/lib/command-not-found ]; then
        /usr/lib/command-not-found -- "$1";
        return $?;
    else
        if [ -x /usr/share/command-not-found/command-not-found ]; then
            /usr/share/command-not-found/command-not-found -- "$1";
            return $?;
        else
            printf "%s: command not found\n" "$1" 1>&2;
            return 127;
        fi;
    fi
}

NOTE: we have to be careful to have "apt-get update" NOT delete its cache, or run it again on startup or something.
