WEBVTT 00:08.870 --> 00:09.550 Hi there. 00:09.620 --> 00:10.610 Welcome back. 00:10.610 --> 00:16.250 Welcome to the final lesson of this section in this list and we're going to learn the more important 00:16.250 --> 00:17.280 commands. 00:17.500 --> 00:19.180 Command is the process. 00:19.250 --> 00:19.810 OK. 00:20.180 --> 00:25.250 The commands are number one and number two is no hope. 00:25.340 --> 00:25.830 OK. 00:25.830 --> 00:32.700 With the help of commands you can do some more airballs stuff as compared to the previous tools. 00:32.700 --> 00:32.960 OK. 00:32.990 --> 00:35.400 So let's see how I could do this. 00:35.840 --> 00:42.300 OK first talk about your future utility your future utility is a powerful tool in Linux. 00:42.300 --> 00:49.190 This utility gives you the information about the file user or the process being currently used by a 00:49.190 --> 00:51.180 file or directory. 00:51.400 --> 00:51.910 OK. 00:52.160 --> 00:54.130 So how do you use this tool. 00:54.190 --> 01:05.760 OK suppose I want to see information about who directory then you need to type if user OK and forward 01:05.830 --> 01:09.460 slash OK for forwards less represent the rubric. 01:09.840 --> 01:12.860 You can see this kind of information here. 01:12.930 --> 01:18.370 It's currently showing us the process id and so access type. 01:18.510 --> 01:19.160 OK. 01:19.400 --> 01:26.730 And if you want to see this information in detail you can provide the search like I've the. 01:26.850 --> 01:35.360 And hit enter key and now you can see clearly here it shows us the user the process ID and it exists 01:35.390 --> 01:36.550 existed. 01:36.570 --> 01:37.100 Come on. 01:37.140 --> 01:37.680 OK. 01:37.920 --> 01:41.030 So here user will get the first user is rogue. 01:41.240 --> 01:42.830 Is process ID. 01:42.830 --> 01:47.480 It's showing here Colonel exegeses mom can come on this route. 01:47.640 --> 01:56.750 The next one is push on process I.D. one of us who've been accessed by P R C and Common's is Tim D. 01:56.790 --> 01:57.140 OK. 01:57.150 --> 02:03.330 So in this very you can get the information about the Directory the root directory is currently being 02:03.330 --> 02:06.580 used by the user Prashant and route. 02:06.750 --> 02:07.180 OK. 02:07.200 --> 02:11.660 So these are the processes that are currently using the root directory. 02:11.940 --> 02:14.090 So what are these axes eggs. 02:14.100 --> 02:16.050 OK so let's see. 02:16.050 --> 02:18.380 So there are different kinds of access type. 02:18.550 --> 02:19.230 OK. 02:19.560 --> 02:21.600 Suppose you get in the output. 02:21.650 --> 02:24.820 See that means it is current directory. 02:24.840 --> 02:29.060 Then if you get it that means it is being run. 02:29.100 --> 02:35.260 If you get that means open find if fees all Miguel in default display mode. 02:35.400 --> 02:41.810 If you get capital left that means you can file for writing and Capital-FM is also omitted in default 02:41.860 --> 02:42.680 display mode. 02:42.840 --> 02:48.160 If you get small that means it is the rope access type group. 02:48.270 --> 02:53.360 And if you get small that means it is managed in a file or shared library. 02:53.460 --> 02:59.640 Here you can see it shows us the pressure is having the access type RNC. 02:59.730 --> 03:07.100 That means you can get a directory and the next process shows us only our That is a group. 03:07.170 --> 03:13.090 So in this way you can get the information in detail with the help of this come on. 03:13.280 --> 03:14.160 OK. 03:14.290 --> 03:18.110 Like c'mon we can also send the kill signal. 03:18.210 --> 03:20.450 We'll get to these processes. 03:20.450 --> 03:27.900 Suppose you want to kill all the processes here then you can simply said I often get a signal and hit 03:28.050 --> 03:29.230 enter. 03:29.490 --> 03:34.360 And now here you can see the entire system restarted. 03:34.590 --> 03:38.410 So let's log in again clear. 03:38.800 --> 03:43.110 And let's run again if he's there. 03:43.360 --> 03:45.470 V. 03:47.170 --> 03:47.730 OK. 03:47.850 --> 03:52.020 Now we kill these processes by sending the signal key. 03:52.200 --> 03:58.200 But suppose there are lots of processes and you want to kill a particular process. 03:58.200 --> 04:02.810 So in such cases you can soon switch like a hyphen. 04:02.850 --> 04:04.930 I use an interactive mode. 04:05.110 --> 04:09.910 OK in which it will ask you whether you want to kill the process or not. 04:10.110 --> 04:16.680 And in this way you can kill a particular process without affecting other processes. 04:16.870 --> 04:17.240 OK. 04:17.250 --> 04:20.940 So just Plourde eye for an eye and he Danka. 04:21.300 --> 04:27.410 OK now here he is asking me if I want to kill one 5 9 4 process. 04:27.870 --> 04:29.100 No. 04:29.480 --> 04:33.110 Asked me for explosives to kill me and I won't press. 04:33.300 --> 04:34.380 Yes. 04:34.710 --> 04:35.630 OK. 04:35.650 --> 04:46.270 And after pressing Yes the there is no file present in our Krongard the slow create a file student last 04:46.310 --> 04:47.450 year. 04:48.210 --> 04:52.990 Now here the file is present and future. 04:53.330 --> 04:56.480 You can get the details of the file system. 04:56.750 --> 04:57.290 OK. 04:57.380 --> 05:04.260 All the processes which are connected to the file system weren't responsible for the file system. 05:04.580 --> 05:10.820 Then you can get the information about good like this overlord in the file as in code. 05:11.200 --> 05:11.780 OK. 05:11.930 --> 05:16.920 And you can also get it in detail by Guarani slash. 05:17.340 --> 05:18.270 OK. 05:18.440 --> 05:25.130 In this way you can see all these processes are related to the file system on which in this file is 05:25.130 --> 05:26.660 present. 05:27.320 --> 05:36.390 In this way you can use the user utility to get information about a particular file user or direct to 05:36.380 --> 05:41.870 user OK or the process which is using the directly or connected to the directory. 05:42.190 --> 05:43.570 OK the next one. 05:43.570 --> 05:45.120 And which is the important command. 05:45.140 --> 05:45.680 OK. 05:45.890 --> 05:52.250 He's no hope no hope is a utility which is used to run a program at the background. 05:52.280 --> 05:54.800 Even if you are Lagat from the system. 05:54.920 --> 05:55.420 OK. 05:55.670 --> 05:59.090 So let's see how it works. 05:59.090 --> 06:03.060 So I want to bring my host that is called off line. 06:03.170 --> 06:07.000 So who said this had the background you just need to type. 06:07.310 --> 06:19.270 No how then big enough to call off line and send it back around again cannot here can't see it displays 06:19.270 --> 06:25.390 the message are ignoring important happening or you know how got that means there's no hope. 06:25.390 --> 06:28.370 God Oxley's glittered in the current directory. 06:28.720 --> 06:41.110 So despite your love of OK now we are logged out type username and password. 06:41.590 --> 06:42.800 OK we are back. 06:43.140 --> 06:49.450 And then here you can see no hope thought out file is created and you can see its contents. 06:49.460 --> 06:54.220 My Gad you know how it got out OK. 06:54.370 --> 06:56.080 And it is the output of the bin. 06:56.080 --> 07:01.570 Come on and you can check it the command is running or not. 07:01.570 --> 07:05.910 With a stop key and type S-3. 07:05.980 --> 07:07.650 So still. 07:07.660 --> 07:08.470 Come on Bing. 07:08.500 --> 07:10.340 And here you can see it is all. 07:10.340 --> 07:19.890 Come on it is running in the background here and you can kill this command by sending the signal 9 and 07:19.900 --> 07:21.260 select your signal line. 07:21.410 --> 07:28.290 Look cool ok and the process stop press and get this stuff clear. 07:28.470 --> 07:33.360 You'll get in this way you can use the fuser and no hope. 07:33.390 --> 07:33.960 Come on. 07:34.000 --> 07:37.070 OK these are the most powerful tools. 07:37.510 --> 07:44.410 So in this way this process management section is very useful for you to manage the processes and make 07:44.410 --> 07:46.790 sure you run your system faster. 07:46.930 --> 07:47.220 OK.
