Time | Narration |
00:01 | Welcome to this spoken tutorial on sed - the stream editor. |
00:07 | In this tutorial we will learn usage of sed command. |
00:11 | We will do through some examples |
00:14 | To record this tutorial, |
00:16 | I am using Linux Operating System and GNU BASH version 4.2.24 |
00:26 | Please note, GNU bash version 4 or above is recommended to practice this tutorial. |
00:33 | As prerequisites |
00:35 | You should know Basics of linux terminal |
00:38 | For relevant tutorials please visit our website which as shown: http://spoken-tutorial.org |
00:44 | Let us with an introduction to sed |
00:47 | sed is a stream editor. |
00:50 | sed finds some pattern of text in a particular location of a file. |
00:57 | It performs some display or editing function |
01:01 | editing function like insertion, substitution and deletion in matched text. |
01:10 | Let us first start with some examples. |
01:13 | We will see how to print using the sed command. |
01:18 | I have a file called seddemo.txt in home directory version. |
01:23 | Let us view its content. |
01:26 | In this file we have some enteries like roll no, name, stream, marks, pass or fail and the stipend amount. |
01:38 | Now suppose we want to print the second line of the file. |
01:43 | For this we need to open the terminal |
01:47 | Now Type |
01:48 | sed space within single quotes ‘2p’ after the single quotes space seddemo.txt |
01:57 | Press Enter |
02:00 | Here 2 denotes the location which is the second line. |
02:05 | p denotes the action, which is printing(p). |
02:09 | Now Look at the output. |
02:11 | It shows the entire file but see that the second line is printed twice. |
02:18 | This is the default behaviour of the action p. |
02:22 | To only print the second line |
02:25 | Type sed space -n space (Within single quotes) 2p after the single quotes space seddemo.txt |
02:37 | Press Enter. |
02:40 | We see only the second line as printed. |
02:44 | -n stands for ‘silent mode’ which will suppress all unnecessary output. |
02:51 | Then we give the location in the stream that we want to edit or display. |
02:57 | We want to select the second line. |
03:00 | p indicates the action we want to take ie to print the second line. |
03:06 | And seddemo.txt is the name of the file |
03:11 | This is the general syntax of sed command. |
03:15 | Now let us print the last line of the file. |
03:20 | Let me clear the promt |
03:24 | Now Type |
03:25 | sed space -n space within single quotes (dollar) $p after the single quotes space seddemo.txt |
03:36 | Press Enter. |
03:39 | We see that the last line is printed. |
03:42 | Now come back to text editor. |
03:45 | Suppose we want to print the enteries from 3rd to 6th |
03:50 | For this we need to type on the terminal: |
03:54 | sed space -n space within single quotes 3 (comma) ,6p’ space seddemo.txt |
04:07 | Press Enter. |
04:09 | The output is displayed from the third line to the sixth line. |
04:14 | Any of the actions can be reversed by using the exclamation mark before the action. |
04:21 | Say if we had to print all lines except from 3rd to 6th we will type:
sed space -n space within single quotes ‘3 (comma) ,6 (exclamation mark) !p |
04:38 | After the single quotes space seddemo.txt |
04:45 | Press Enter. |
04:46 | The output is displayed. |
04:49 | Let us switch back to our slides. |
04:52 | Line addressing and context addressing. |
04:56 | So far, we specified the lines in the file on which the action needs to be taken. |
05:02 | This is known as line addressing. |
05:05 | Address specified by the line numbers. |
05:08 | This is one way of addressing. |
05:11 | Another way of addressing is Context addressing |
05:16 | Lines that contain particular context say a particular word. |
05:21 | If we want to take actions on lines that contain a particular word we use context addressing. |
05:29 | Regular expressions can be used. |
05:32 | Let us see an example. |
05:35 | Come back to our editor. |
05:38 | Say we want to print those lines which have the word computers. |
05:44 | Come back to our terminal. |
05:46 | Now Type |
05:48 | sed space -n space (within single quotes) (front slash)(opening square bracket) [cC] (Closing Square bracket) omputers/p after the single quotesspace seddemo.txt |
06:14 | Press Enter. |
06:16 | We see the lines with the word computers is displayed. |
06:22 | We write pattern within square brackets. |
06:24 | This is to match any one or both of the characters within square brackets. |
06:30 | When we need to match patterns the pattern needs to be typed between front slashes. |
06:37 | We can print it in file as well using the w option. |
06:43 | For this type: |
06:44 | sed space -n space (within single quotes) (front slash) (opening square bracket) [cC] (closing square bracket)omputers/w space computer_student.txt after the single quotes space seddemo.txt |
07:11 | Press Enter. |
07:14 | Now all the matching lines would be transferred to the file computer_student.txt. |
07:21 | Let us view the content |
07:25 | Type cat space computer_student.txt |
07:32 | Press Enter. |
07:35 | We see the entries |
07:37 | We can also have patterns that we can write to different files. |
07:42 | Let us clear the promt |
07:45 | Type sed space -n space -e space (within single quotes) (front slash) ‘/electronics/w space electro.txt’ after the single quotes space -e space (within single quotes) (front slash) ‘/civil/w space civil.txt’ after the single quote space seddemo.txt |
08:18 | Press Enter |
08:22 | Here -e is used to combine multiple methods |
08:27 | This would create two files electro.txt and civil.txt. |
08:34 | To see what they contain type: |
08:37 | cat space electro.txt |
08:42 | This will display the enteries with the word electronics. |
08:47 | Let us see the content of civil file. |
08:50 | Type cat space civil.txt |
08:55 | press Enter |
08:57 | This will display the enteries having the word civil. |
09:01 | We will see some more set of commands in another tutorial. |
09:05 | I will use the same program. |
09:08 | This brings us to the end of this tutorial. |
09:11 | Let us switch back to our slide |
09:14 | we will summarize, |
09:15 | In this tutorial we learnt,sed |
09:18 | To print using sed. |
09:19 | Line Addressing. |
09:21 | Context Addressing. |
09:23 | As an assignment, |
09:25 | Use the same text file seddemo.txt. |
09:28 | Try to print records from 6th to 12th line. |
