WEBVTT 00:05.560 --> 00:11.230 So in the last lesson, during a couple of scripts, I mentioned the word cheroot and went over it kind 00:11.230 --> 00:11.840 of briefly. 00:12.220 --> 00:17.800 So in this lesson, what I thought I do is do more of a deep dive into a root so you can better understand 00:17.800 --> 00:18.430 what it is. 00:19.440 --> 00:25.530 All right, so right now I'm booted from recovery and I'm going to go to a terminal, and so this is 00:25.530 --> 00:30.720 kind of like the same environment we would have been in if we were doing bootstrap or we're in the recovery 00:30.750 --> 00:31.460 environment. 00:31.830 --> 00:38.690 So if I go ahead and take a look at where I am now, I'm basically in route's home folder. 00:38.820 --> 00:45.210 And if I go ahead and I try to create a directory, it says that I'm in a read only file system. 00:45.390 --> 00:50.190 And that's because the recovery partition is a read only image. 00:51.200 --> 01:01.640 So if I don't see you till I get my computer name, then you see it returns, Mac, and if I do a get 01:01.640 --> 01:04.580 hostname, you can see it's not set. 01:05.120 --> 01:09.400 Now, remember, we talked about that computers out of the box don't get a hostname. 01:09.980 --> 01:19.280 And so in this read-only recovery partition bood environment, the computer name was said by Apple to 01:19.280 --> 01:19.740 Mac. 01:21.110 --> 01:24.480 So let's go ahead and cheroot into Macintosh hard drive. 01:24.900 --> 01:31.410 Now notice what our prompt says are shall prompt says it, says Basche right now. 01:31.820 --> 01:37.130 Now I'm going to go ahead and Trute as user route into volumes. 01:37.130 --> 01:38.240 Macintosh Hard Drive. 01:38.960 --> 01:47.840 And you see now my prompt has changed and if I see where my current directory is, you can see I've 01:47.990 --> 01:49.110 also changed. 01:49.760 --> 01:57.950 Now if I go into my home directory, you can see that's Bahru and if I make a directory test, it stays 01:57.950 --> 02:02.290 there because I'm in a read right file system. 02:02.330 --> 02:07.340 I'm on the Macintosh hard harddrive now on a Macintosh hard drive. 02:07.910 --> 02:10.930 The user's folder is in the root of Macintosh hard drive. 02:10.940 --> 02:13.160 So if I go to see one user's. 02:14.430 --> 02:15.810 You see, it works. 02:15.840 --> 02:21.120 I'm in the user's folder, and if I do a listing, you can see that I've got my administrator shared 02:21.120 --> 02:29.370 and my Mojave folders and I can even go into the have a folder into the in into the documents folder 02:29.580 --> 02:32.310 and see what was it and see if there was anything in it. 02:33.620 --> 02:36.470 Now, if I exit the Trute environment. 02:37.680 --> 02:47.820 And I try to go to users, it's it's not there there is no directory if I go to the root of the recovery 02:47.820 --> 02:48.630 partition. 02:49.870 --> 02:58.090 You can see that I don't have a user's folder now if I commute back into. 02:59.920 --> 03:02.620 The Macintosh hard drive and I go to route. 03:03.600 --> 03:08.250 You can see that my file system looks different and I have the user's folder. 03:09.420 --> 03:14.670 All right, so we're in the current environment and what we did in one of the scripts is we renamed 03:14.670 --> 03:15.350 the computer. 03:15.930 --> 03:24.600 Now if I do and Sue to get computer name, you can see I'm getting the computer name return because 03:25.050 --> 03:27.900 I'm basically logged into the Macintosh hard drive. 03:27.990 --> 03:33.480 And whatever commands I type in, I'm going to get returned like I'm logged into the Macintosh hard 03:33.480 --> 03:33.810 drive. 03:34.260 --> 03:44.670 So again, I could do get hostname and I see that I get my proper name and as soon as I exit and I type 03:44.670 --> 03:52.230 in the exact same command, now I get different results because now I am applying commands to the file 03:52.230 --> 03:55.590 system in which I'm booted, which is the recovery partition. 03:56.400 --> 04:01.950 So I hope that clarifies what a Cerruti environment is and why I was using it. 04:01.950 --> 04:02.830 And bootstrappers.
