 Okay, this is going to be a quick one. So let me say I want to do something as sudo. So I'll just sudo echo hello. Right, ask for my password. I'll type my password. You get no feedback on what you're going on, which is good in a security sense. People can't see how long your password is, but it's kind of nice sometimes to have some feedback. So let's add some feedback to that. So we're going to sudo vi sudo. So vi sudo is like vi or vim to edit your sudo's file, your sudoer's file, which will check and make sure you don't screw it up because that can mess up your system. So if you're going to edit your sudoer's file, use vi sudo. So I will type in my password. And you just come down here to defaults and you have env reset du comma pw feedback. So pw password feedback. Go ahead and save that file. And now if I sudo, well, I need to open up a new shell because my password's saved there. I'm just going to sudo echo hello. And okay, I'll open up a new shell down here, sudo echo hello, obviously my save password copied over there. So now if I type in whatever my password is, you get a little asterisk feedback there so you know that you're typing in something's actually happening. Again, some may view this as a security risk because if I'm like this, you're like, oh, I know exactly your password's eight characters, maybe it's password, which it's not. But for me, I kind of like it depending on the system and if you have someone looking over your shoulder. So that's it. I hope you found this useful. And visit filmsbychris.com.
