00:00:01,080 --> 00:00:09,420
‫So redirection is a feature in Linux, so that when executing a command, you can change the standard

2
00:00:09,420 --> 00:00:11,190
‫input output devices.

3
00:00:12,890 --> 00:00:17,870
‫The standard input device, of course, is a keyboard in the standard output device is the screen.

4
00:00:20,420 --> 00:00:21,290
‫But check this out.

5
00:00:21,770 --> 00:00:27,170
‫A single greater than symbol is used to overwrite the output file with the result set.

6
00:00:29,980 --> 00:00:35,710
‫The double greater than symbol is used to upend the result set to the target file.

7
00:00:37,410 --> 00:00:42,960
‫The single less than symbol is used to add the results as an input for another command.

8
00:00:44,950 --> 00:00:50,860
‫As you may remember, we practiced output redirection while running the cat in echo commands.

9
00:00:51,310 --> 00:00:52,300
‫I wonder if you noticed?

10
00:00:53,200 --> 00:00:56,380
‫Well, let's try it here and see if you recognize.

11
00:00:57,400 --> 00:01:03,160
‫So first run, Echo Hello, World, single greater than my text file.

12
00:01:05,090 --> 00:01:06,620
‫Now, look at the content of the file.

13
00:01:07,550 --> 00:01:08,840
‫We overwrite the file.

14
00:01:10,320 --> 00:01:13,080
‫So this time, let's use a double greater than symbol.

15
00:01:14,770 --> 00:01:17,680
‫And this time we add a new line to the text file.

16
00:01:28,520 --> 00:01:30,560
‫So let's use input redirection.

17
00:01:32,980 --> 00:01:40,000
‫So in the previous lectures, we looked at the Etsy or Etsy slash password file, and that contains

18
00:01:40,000 --> 00:01:41,800
‫a list of the system's accounts.

19
00:01:42,860 --> 00:01:45,740
‫There were some values on a line separated by a colon.

20
00:01:46,800 --> 00:01:53,460
‫Run cut, dash de colon dash F1 less than ETSI slash password.

21
00:01:54,930 --> 00:01:59,760
‫So in the first command, we got the first values of each row with the dash of one parameter.

22
00:02:00,940 --> 00:02:07,540
‫We needed a delimiter to separate them, and we use the colon for this with the dashti parameter.

23
00:02:09,270 --> 00:02:16,830
‫So he gave the Etsy slash password file as the input to the first command by using input redirection.

24
00:02:19,340 --> 00:02:22,180
‫So do you remember what this fire looked like before?

25
00:02:23,460 --> 00:02:26,190
‫And as you can see, we extracted the first column of each line.
