1 00:00:06,570 --> 00:00:07,403 - All right. 2 00:00:07,403 --> 00:00:08,236 Let's have a look 3 00:00:08,236 --> 00:00:10,080 at the commands that we've seen in this lesson. 4 00:00:10,080 --> 00:00:12,750 We started with top, top is probably the most 5 00:00:12,750 --> 00:00:14,760 important command that you've learned about 6 00:00:14,760 --> 00:00:16,980 because you can monitor all processes 7 00:00:16,980 --> 00:00:19,533 in the generic state of health of your system 8 00:00:19,533 --> 00:00:21,930 from a performance perspective. 9 00:00:21,930 --> 00:00:24,697 PS is a very convenient command that allows you 10 00:00:24,697 --> 00:00:28,320 to monitor all processes in their properties. 11 00:00:28,320 --> 00:00:33,180 Jobs is what the user can do to manage their own jobs, 12 00:00:33,180 --> 00:00:36,090 which are processes that the user has started 13 00:00:36,090 --> 00:00:38,940 as interactive processes in the shell. 14 00:00:38,940 --> 00:00:41,940 FG is for foreground and BG is for background. 15 00:00:41,940 --> 00:00:43,740 And that's something that you can do 16 00:00:43,740 --> 00:00:45,990 with jobs running in the shell. 17 00:00:45,990 --> 00:00:48,540 Now we have nice, which you can use to start a process 18 00:00:48,540 --> 00:00:52,800 with just a priority or renice to, 19 00:00:52,800 --> 00:00:56,760 to change the priority for a currently running process. 20 00:00:56,760 --> 00:00:58,470 Kill is how you can send a signal 21 00:00:58,470 --> 00:01:01,530 to a process which is normally used to stop it 22 00:01:01,530 --> 00:01:03,630 and kill all is doing the same. 23 00:01:03,630 --> 00:01:06,120 The difference is that kill by default works on PID 24 00:01:06,120 --> 00:01:08,520 and killall will work on names. 25 00:01:08,520 --> 00:01:09,353 That's all. 26 00:01:09,353 --> 00:01:10,470 Let's go check out the lab.
