Linux Homework Support Needed

I need help with my Linux homework. This assignment requires you to use the terminal and provide screenshots where specified ITN 170 Assignment 2 This assignment is a comprehensive practical lab designed for the Ubuntu virtual machine within the VA Cyber Range. The assignment is structured to build proficiency in Linux file management, system administration, and environment customization through five distinct parts, collectively emphasizing the use of the command-line interface and text editors like vi and nano Part 1 The chmod and chown commands. This part of the assignment is worth 20% of the assignment grade. Please provide a screenshot as requested through this assignment document. This assignment is designed for the Ubuntu virtual machine in the VA Cyber Range. We went through the chmod command in assignment 1 using the numerical method. Now let’s use the chmod command using the character method. To change file and directory permissions: Make certain that you are in your home directory. Use the touch command to create a file named corp_db Use the vi editor to enter the text shown below. Assignment [login to view URL] Press escape + shift :wq to save the file. Type chmod ugo+x corp_db and press Enter to allow access to the corp_db. (Screenshot) This command means “make the corp_db directory accessible (+x) for the owner (u), group (g), and others (o) Type chmod ugo-x corp_db and press Enter to remove permissions corp_db directory. (Screenshot) Type ls -l corp_db Notice that the file does not have any permissions. Repeat step 6 to restore the permissions for corp_db Do not delete the corp_db file. You will need it for the next exercise. To change the owner of a file: Log in as the root user Type useradd user1 Type passwd user1 assign the password student Type ls -l corp_db notice that the owner of the file is the root user. (Screenshot) Type chown user1 corp_db Type ls -l corp_db This should indicate that the new owner of the file is user1 (Screenshot) That’s all there is to changing the owner of a file or directory. Type head corp_db (Screenshot) Type tail corp_db (Screenshot) Part 2 Some more file commands. This part of the assignment is worth 20% of the assignment grade. Use the touch command to create file1 Enter some text into the file Type: file file1 Screenshot The file1 file is an ASCII text file, which means it contains basic text. Use the mv command to rename file1 to revised_file Type mv file1 revised_file Screenshot Use the stat command to view the attributes of revised_file Type stat revised_file Screenshot Use the mkdir command to create a directory named Management. Use the same command to create a directory named Payroll inside the Management directory. Use the touch command to create a file named paychecks inside the Payroll directory. Use the nano editor to enter some random text into paychecks. Here is the syntax to accomplish this: mkdir Management cd Management mkdir Payroll cd Management/Payroll Type nano paychecks Type some text into the paychecks file. When you are finished press Ctrl + X and type y to save the contents of the file. Use the copy command to copy the Management directory that you created to a directory named Directory. Type cp -r Management Directory Type ls -l to view the new directory Screenshot Change directories into the Management Directory The tee command will copy the contents of a directory and show the contents while copying: Type ls -all | tee files Screenshot Part 3 Symbolic and Hard links. This part of the assignment is worth 10% of the assignment grade. Create a symbolic link to the Management directory which you created. The link will appear in the home directory. Screenshot the link. Type: ln -s Management Home Make sure that you are working in the Payroll directory. Create a hard link to the paychecks file that you created. This will create a copy of the contents of paychecks in the home directory. The link will appear in the home directory. Screenshot the link and the contents of the file in the home directory. Part 4 Aliases - This part of the assignment is worth 30% of the assignment grade. printenv | more screenshot printenv SHELL PATH screenshot To create a variable, and assign it a value: Type HOCKEY=Capitals and press Enter. You’ve created the variable HOCKEY. To see the contents of a variable: Type echo $HOCKEY and press Enter. You see the word “Capitals.” Take a screenshot of the output and paste it into your lab document. Type MEMO="Meeting will be at noon today" and press Enter. Type echo $MEMO and press Enter. (Screenshot) You see the contents of the MEMO variable: Meeting will be at noon today. Take a screenshot of the output and paste it into your lab document. To create an alias called ll for the ls command, type alias ll="ls -l", and press Enter. Now, when you use the new ll alias, the ls -l command executes automatically. Test the alias by typing ll and pressing Enter. You see a long directory listing. Take a screenshot of the output and paste it into your lab document.
