If we look at the file, we see this in a "factory" Debian 10 (Buster) system: This file is never edited directly, but is used for this purpose visudo command: The file typically contains entries such as who can run which command (s) using sudo, and so on. The sudoers fileĪ / Etc / sudoers file contains the rules that the sudo command takes into account when using it. It allows you to delegate tasks such as the entire server or some of its services (e.g. Sudo is a useful little tool on Unix-like operating systems that allows you to run commands or programs on behalf of other users, typically as root. In this short description, we will look at how to persistently avoid asking for a password when using sudo. And if you also want to use commands running with root privileges in Shell scripts, you definitely need to avoid typing passwords so that our programs can run automatically. Also, if you work with multiple users, you will need our passwords more often. Although the session "remembers" the previously entered password for a while, we don't have to retype it for a while, but we need to re-identify ourselves after a while. When you often need the sudo by using other commands as root you may need to not have to type the password every time. Run Sudo commands without using a password.I am not in favor of running sudo w/o passwds, that was never my point, but I am also not in favor of a re-authentication hurdle every few minutes. If I have to perform some local sysadmin function I don't use the terminal session I've been using for development - I segregate that to another (pink bkgnd) terminal that is exclusively for that purpose and delete it when done. I script up the several steps that require privilege and try to just execute these (by command recall) and nothing else - anything else requires much care. I know instinctively that the pink/red background root terminal deserves respect, and the straw-yelllow bkgnd is the remove development system, and. I have to stay alert to what I am doing, but that's exactly the price power demands, but I've given myself a big advantage by making it very easy to see the issue visually and then I can assess the risks. After accidentally typing commands in the wrong window (years ago) I started color coding them (different background text color), and putting related terminal sessions in a single window as tabs, sometimes even changing the font size. I often/usually have a bunch of terminal sessions open to different systems, remote development systems, embedded systems behind vpns or on my office, other systems in my office, and yes for some projects I have a window open as local root. You "just type it" to get over the tedious hurdle. Guard ralis and seat belts and redundant authentication challenges and "are you sure?" queries all lead people to adjust their behavior to more risky behavior. It's so tedious that it strongly encourages you to ignore and type.Įsp see the Peltzman effect & Risk homeostasis. Once you've seen it enough to get tired, you just ignore it. Once you've entered the passwd a dozen times in the past hour you just do it out of "muscle-memory". Typing vs doesn't help you understand what "something" did. If it doesn't you have no idea what just got done.Either way - you still have no idea what it's done.
