Time Narration
00:00 Hello and welcome to the Spoken Tutorial on Simple Filters with Linux.
00:08 Here we will be learning about head, Tail, sort, cut and paste.
00:17 All these are command line text manipulation tools.
00:22 If you see a hash (#) symbol on the Terminal, you need to become root to execute those commands.
00:29 sudo su or su root, if you see a dollar symbol on the Terminal you can be an ordinary user to execute those commands.
00:38 I assume that you did a default installation and did not modify any path where the files are getting saved.
00:46 I am using Ubuntu 10.10 for this tutorial.
00:51 Prerequisites for this module are the ability to use the mouse , keyboard, maximize and minimize buttons on a window.
01:02 We use the Head command followed by an ascii file name, to display the first 10 lines of a file by default.
01:10 Let us create a file. I am hitting on Esc (escape) key to show this practically.
01:17 Go to Applications > Accessories > Text Editor.
01:24 I already have these numbers in another file for the sake of time constrain.
01:30 Let me copy and paste.
01:38 Hit on File ,Save.
01:41 Name the file as numbers dot txt and hit on Save.
01:48 Close this file.
01:53 Now go to Applications > Accessories > Terminal.
02:01 Let us try to see if we can see the file we created.
02:05 Type ls and hit on Enter.
02:09 What we did here is to list all the folders and files on our home directory.
02:15 Now we can use the cat command to read the contents of the file we created.
02:21 Cat n-u-m Hit on tab to autofill the file name. Hit on Enter.
02:29 Let us do the same with head command.
02:33 head numbers dot txt, Enter.
02:39 Now the first 10 lines are displayed.
02:43 If we want to see the first 5 lines, use the option hyphen n5 in between the head command and the file.
02:52 Hit on Up arrow, hyphen n5 and Enter.
02:58 Now the first 5 lines alone are displayed.
03:02 Let us switch back to the presentation.
03:08 F5
03:14 The tail command works exactly opposite to the head command, it displays the last 10 lines of a file by default.
03:22 I am hitting on ALT and Tab to switch to the terminal.
03:27 tail numbers dot txt
03:31 If we want to see just the last 5 lines, use the option hyphen n5 in between the tail command and the file name.
03:40 hyphen n5, Enter.
03:45 Switch to slides.
03:50 A log file contains events which took place in a system.
03:55 Auth dot log file maintains log's for who logged in & who logged out.
04:01 The most useful option of the tail command is to use hyphen f option to follow the tail of a log file.
04:09 If a new line is appended to the log file, the tail command will take that as the last line and display 10 lines by default above it.
04:18 Go to the terminal.
04:21 tail hyphen f forward slash var slash log slash auth dot log
04:31 Let me resize this terminal.
04:39 Let us open another Terminal, Application -> Accessories -> Terminal.
04:46 Let me resize this terminal
04:52 so that I can show you in a single screen how tail follows the last line in a log file.
05:00 Try to su as yourself, hit on Enter.
05:05 Give in some wrong password hit on Enter.
05:08 You will see that the terminal on which tail is running is appended with a new log.
05:15 The date & time specifies when the authentication failure took place.
05:23 Type date, hit on Enter to verify the system date and time.
05:32 Type Exit to close this terminal.
05:36 Hit CTRL C to close the running tail command & maximize the screen.
05:51 We have seen only auth dot log file in the previous example.
05:57 These are the commonly used log files in Linux.
06:01 A Linux system administrator will look into these log files for more information to troubleshoot his machine if there is a problem.
06:12 Sort command, as the name suggests, will sort a file for us in both ascending and descending order.
06:23 sort numbers dot txt. This would sort our numbers dot txt file in ascending order.
06:31 Notice something is strange in there, sort just looks at the first character to sort, so 10,11&12 appears before the number 2.
06:43 To avoid this, add the option of hyphen n hyphen n and Enter.
06:53 Now sort looks at the entire number to sort them.
06:58 To sort number dot txt in reverse order add an option of hyphen r.
07:09 We have numbers that repeat in this file, to pull out just the unique numbers add another option of hyphen u .
07:17 Go to Terminal.
07:20 Up Arrow
07:22 U, Enter.
07:26 Previously two 2's were displayed . Now only one 2 is displayed.
07:38 Now we will see how we can sort a file based on certain column.
07:44 Let us create a file and key in these as shown below.
07:48 Go to Applications > Accessories > Text Editor.
07:57 I already have the data in another file for the sake of time constrain, let me copy & Paste the value, CTRL+C; CTRL+V.
08:11 File, Save it as marks dot txt, Hit on Save.
08:21 Don't mind the special characters on this file. I don't want someone to sue me for giving them low marks.
08:28 Close this file.
08:33 Let us sort based on the second column of marks dot txt file.
08:40 Go to the terminal.
08:42 sort space marks dot txt space hyphen t space open inverted commas space close inverted commas space
08:53 Here, hyphen t stands for the delimiter & the space in between the quotes represents it.
09:02 hyphen k2 for the second column on which sort should be performed.
09:14 Hit on Enter.
09:20 Cat marks dot txt
09:24 This is the original file, if you see Avir is moved above and Bala came below when we sorted based on the second column alone.
09:43 Cut command is used to cut just certain information from a file.
09:51 Let us pull out the names from marks dot txt.
09:55 Let us go to the terminal ALT Tab,
09:58 cut space marks dot txt space hyphen d space open inverted commas space close inverted commas space.
10:08 Here, in cut command d is the delimiter & the space in between the quotes represents the delimiter.
10:20 hyphen f2 for the second column. Hit on Enter.
10:31 Paste command will merge corresponding subsequent lines of the files.
10:36 Let us use both the numbers dot txt and marks dot txt files now.
10:41 Go to the terminal.
10:43 Paste numbers dot txt marks dot txt, Enter.
10:50 Now the first line of marks dot txt was appended to the first line of numbers dot txt.
10:57 We can use the redirect key to redirect this output to some other file called concatfile dot txt.
11:06 Go to the terminal.
11:08 Hit on Up arrow. Hit on the redirect key which is the Greater than symbol (>) concatfile dot txt. Hit on Enter.
11:18 Cat concatfile dot txt
11:22 Let us go to the slide.
11:25 If we want paste to print out the numbers serially delimited with tab, we can use the hyphen s option.
11:34 Paste hyphen s
11:39 numbers dot txt
11:43 Go to the slide.
