Time Narration
00:02 Hello and welcome to the Spoken Tutorial on Basics of System Administration in Linux.
00:09 In this tutorial, we will learn the following-
00:13 adduser su
00:16 usermod userdel
00:18 id du
00:20 df
00:22 I am using Linux for this tutorial.
00:27 As a prerequisite, please go through the spoken tutorial on General Purpose Utilities in Linux which is available on this website.
00:39 One must have admin access in order to execute the commands shown.
00:47 Let us first learn how to create a new user.
00:53 The adduser command will create a new user login for us along with authentication.
01:01 We can add any user account with the help of sudo command.
01:06 Let me give you a brief explanation about the sudo command.
01:11 Sudo command allows the administrative user to execute a command as a super user.
01:19 The sudo command has many options. We will learn about the options as we go further in this tutorial.
01:27 Let's now learn how to create a New User.
01:32 I have already invoked the Terminal here.
01:36 Here, type the command: sudo space adduser and press Enter.
01:45 You will be prompted for a password.
01:48 I will give the Admin password here and Enter.
01:54 The typed password on the terminal is not visible.
01:58 So, we have to type the password carefully.
02:03 Once done, a message "adduser : Only one or two names allowed" is displayed.
02:14 So, let us create a new user account named duck.
02:21 Type the command :
02:23 sudo space adduser space duck and press Enter.
02:33 We have created a new user called "duck".
02:36 In the process of creating a new user, a separate home directory for that user has also been created.
02:46 Please note that we will be prompted for a new password for the user duck.
02:52 Type the password of your choice, in my case I am going to type "duck" as the password and press Enter.
03:04 Please type the new password again.
03:07 The password is asked twice for security reasons and for confirmation.
03:13 Now our password for the new user is updated.
03:18 We will be asked for other details too.
03:22 But for the time being, I will enter only the Full Name as "Duck" and leave the rest of the details blank by pressing the Enter key.
03:33 Enter.I will confirm this by entering “y”.
03:39 This is to confirm that all the information is correct.
03:43 Let us now check, if the user account has been created.
03:48 To do this, please type at the command prompt:
03:51 ls /(slash) home
03:56 and press Enter.
03:58 To show the list of users in the home folder this command is used.
04:05 And, here is our newly created user named "duck".
04:10 Let me switch back to the slides.
04:13 Now the next command is the su command.
04:18 su stands for Switch User.
04:21 This command is useful for switching from the current user to another user.
04:26 Let us go to the Terminal now.
04:30 Enter the command: su space hyphen space duck on the terminal and press Enter.
04:41 You will be prompted for a password.
04:44 I shall type the user duck password here, please recall that it was "duck" itself.
04:51 Please notice that, the Terminal switches from the previous user to the new user which is “duck” in our case.
05:02 To logout from this user, type logout and hit Enter.
05:10 Now the terminal logs out from the current user duck and comes back to the previous user account which is vinhai in our case.
05:18 Let us learn about the usermod command.
05:23 The usermod command enables a super user or root user to modify the settings of other user accounts such as:
05:33 Change the password to no password or empty password.
05:37 Show the date on which the user account will be disabled.
05:42 Let us try this command and see.
05:44 Let me switch to the terminal now.
05:46 Let me show you how to set a date of expiry for the user account duck.
05:52 Here, at the command prompt, type:
05:56 sudo space usermod space -(hyphen)e space 2012-(hyphen)12-(hyphen)27 space duck
06:21 and press Enter.
06:25 The user account expiry date is set as mentioned in the command here with the help of the option “-e”.
06:34 Now you have set an expiry date for the user account duck.
06:39 Let us now talk about the uid and gid commands.
06:45 id – command is used to check the identities of all the users and groups.
06:51 To know about the identity of the user, we use id space -(hyphen)u.
07:00 To know about the identity of the group users, it is id space -(hyphen)g.
07:08 Now let's work on this.
07:10 At the terminal, let us type id and press Enter.
07:17 Now, we can see the User IDs and Group IDs on the system that we are using.
07:25 To get only the user-id, we use “-u" (hyphen u) option.
07:30 Let us type the command: id space -(hyphen) u
07:36 and press enter.
07:38 Now, we can see only the 'id's of the users.
07:42 But what if we need to know the names of the users?
07:47 To find that out, we will type:
07:50 id space -(hyphen) n space -(hyphen) u on the terminal here and press Enter.
08:00 Now, we can see the names of the users instead of their 'id's.
08:08 Let us now learn the commands for Group IDs.
08:12 Let's type: id space -(hyphen)g.
08:17 Here we can see the group ids.
08:20 If we want to view all the current user's group IDs, type:
08:26 id space -(hyphen) (capital)G and press Enter.
08:32 Please notice that I have typed 'G' in capital letter.
08:38 See the result for yourself.
08:40 Now, let us learn how to delete a user account.
08:44 For this, we use userdel command.
08:48 We can delete an user account permanently with the help of the userdel command.
08:54 Let's try this on the terminal.
08:56 Here, type: sudo space userdel space -(hyphen)r space duck.
09:09 I have used the '-(hyphen)r' option.
09:12 This is to remove the user along with his home directory.
09:17 Let us press Enter and see what happens.
09:21 Now the user duck has been deleted.
09:25 Check this by typing:
09:28 ls space /(slash) home and press Enter.
09:35 We will find that the user account duck has been deleted.
09:40 Let me go back to the slides now.
09:43 Some of the useful commands in Linux System Administration are “df” and “du”.
09:50 The df command gives a report on the free space available on the disk.
09:55 And the du command gives a report on how much space a file has occupied.
10:00 Please try these two commands and find the output for yourself as an assignment.
10:06 Let us shift to the terminal. I shall show you a few useful options used with the “df” command.
10:13 Please type: df space -(hyphen)h and press Enter.
10:20 Here, it shows the size of the File system and the space used.
10:25 It also shows the space mounted on, in a human readable format.
10:34 Let us now try some options with the “du” command.
10:37 At this point, I assume that you have created some text files in your home folder.
10:44 If not, please refer to the tutorial on General Purpose Utilities in Linux.
10:51 I have already created some text files in my home directory to execute the commands.
10:58 Go to home folder on the terminal by typing:
11:03 cd space /(slash) home and press Enter.
11:07 Then, type: du space -(hyphen)s space *. (asterisk dot) txt and press Enter.
11:21 This command will give you a report on the txt files available in the directory along with its file sizes.
11:30 As an assignment, at the command prompt, please type:
11:35 du space -(hyphen)ch space *.(asterisk dot) txt and see what happens.
11:46 Let me go back to the slides.
11:48 To summarize, we have learnt:
11:51 "adduser" command to create a new user.
11:53 “su” command to switch from one user to another user.
11:56 “usermod” command to change the user account settings.
12:00 “userdel” command to delete the user account.
12:03 "id" command to know the information about user ids and group ids.
12:07 “df” command to check the file system size and its availability.
12:11 “du” command to check the space occupied by a file.
12:15 This brings us to the end of this tutorial on “Basics of system administration”.
