Using Linux in VirtualBox Do the Following Exercise:

Using the clear command

At this point, you screen might seem filled with commands and their results. Use the clear command anytime you want a clean slate. This exercise enables you to clear the screen now.

To clear the screen:

1. Type clear on the command line, and press Enter. The command prompt is now in the upper-left corner of your screen. [No output or questions for this part.]

Viewing manual pages

You can use the manual pages to learn more about a command or program (if the program is documented in the manual pages). In addition, the whatis command provides a quick summary of specific command and programs. You use both the man and whatis command in this exercise. The database for the whatis command should already be created prior to using the command.

To display online help using man:

1. Type man who in the command line, and press Enter. Do you see the explanation of the who command?                                                                         
2. Press Enter one or more times to view additional lines of text. Next press the spacebar to view additional pages of documentation.
3. Type q to exit the man program.
4. Type man man and press Enter. You see the man page describing the man command. What is the purpose of the –M option?
5. Type q to exit the man program.

To display a brief description of a command with the whatis command:

1. Type whatis who and press Enter.
2. Do you see a summary of the who command? Record it here:                                                     

Editing command-line input

[Do all 11 steps, but there is no need to record the output for your report.]

Entering multiple commands

You can execute multiple commands on one command line by using a semicolon between commands. You will practice running multiple commands in this assignment.

To enter multiple commands on the command line:

1. Type date; cal and press Enter to view the current date and this month’s calendar. Record your screen:                                                                                                                           
2. Type date; who –uH and press Enter. The date command produces the first line of the output; the remainder of the output is the results of the who command. Record your screen:                                                                                                                                                             

Using command history

In this assignment, you will use the command history capability of the Bash shell to recall commands you have used earlier. As you’ll discover the more you use Linux, this command can save a lot of time otherwise spent on repeated typing.

To use the command-line history:

1. Type date and press Enter.
2. Type who and press Enter.
3. Type who –uH and press Enter.
4. Type clear and press Enter.
5. Press the up arrow key four times, the date command is recalled to the command line. Do not press Enter.
6. Press the down arrow key twice. What command do you see?                                                    Press Enter to execute the command.

Changing your password

Your password is your means to protect your user account from others who might attempt to access it without your authorization. Plan to change your password often to keep your account secure. In this assignment, you will learn how to change your password.

To change your password:

[Do steps 1-4, but there is no need to record the output for your report.]

Using the cat command

The cat command has several purposes, but one of the most commonly used is to view the contents of a file. For example, in this assignment, you use the cat command to view a file called shells that resides in the /etc directory. This file contains a list of valid shell programs available through Linux.

To use cat to view the shell’s file:

1. Type cat /etc/shells after the command prompt, and press Enter (the forward-slash (/) is used to indicate a directory or folder change.) What do you see on your system?                                                                                                                                                                       
2. Sometimes, it is helpful to see a file’s contents displayed with line numbers. The –n option causes the cat command to display a number at the beginning of each line of output. Type cat –n /etc/shells and press Enter. You should see the same list of shells as before, but his time a number precedes each line.

Redirecting command-line output to a file

You already used the who command to find out who is logged in to the computer. In this assignment, you will use the same command with the > redirection symbol to save this information in a text file.

To save a file that lists the persons logged into the system:

1. Make sure you are under the directory of /home/user, or type cd to move to the /home/user directory.
2. Type who > current_users after the command prompt, and press Enter. The who command output does not appear on the screen but is redirected to a new disk file called current_users. Linux places this text file in the active directory (the directory on the disk where you are currently using the system).
3. Type cat current_users after the command prompt, and press Enter to see a list of users currently using the system. Record your output:                                                             

Redirecting calendar output to a file

You can also use the redirection symbol with the cal command to save a calendar in a text file. For example, assume that you are involved in a development project with a projected deadline in the year 2018. You can save the calendar in a text file.

To save the year 2018 calendar in a file.

[Do steps 1-3, but there is no need to record the output for your report.]

Creating a new file with information you type in

As you work with Linux, suppose you remember that your instructor asked you to complete a few tasks by the end of the week. In this project, you will create a notes file to serve as a task reminder using the cat command with the > redirection symbol.

To create a new file:

1. Type cat > notes after the command prompt, and press Enter.
2. Type the following: Remember to order a new CD-ROM, and send the report by Thursday, and press Enter.
3. Press Ctrl+d.
4. To review the file you just created, type cat notes after the command prompt, and press Enter. The sentence you typed in step 2 should appear on the screen. Record your screen:                                                                                                                                                                  

After you create the notes file, let’s say you remember that your instructor also asked you to complete another task. You can append this second reminder to the existing notes file. You also want to include the appropriate monthly calendar in the file for reference.

To add information to an existing file:

1. Type cat >> notes after the command prompt, and press Enter.
2. Type the following: Also remember to make reservations for Sept. conference, and press Enter.
3. Press Ctrl+d.
4. To add the September calendar to your notes, type cal 9 2018 >> notes and press Enter.
5. Type less notes and then press Enter to review the file. Record your observation:                                                                                                                                                                       

Type q to exit the file
