Save the file in a directory named homeworks that you would have created. Set the permissions for this file such that only you can edit the file while anybody can only read. Find and list (on the command prompt) all the statements that contain the word POINTS. Submit your answer as a description of what you did in a sequential manner

Answer 1

Answer:

mkdir homeworks    // make a new directory called homeworks.

touch homework_instructions.txt //create a file called homework_instruction

sudo -i    // login as root user with password.

chmod u+rwx homework_instructions.txt  // allow user access all permissions

chmod go-wx homework_instructions.txt // remove write and execute permissions for group and others if present

chmod go+r homework_instructions.txt  // adds read permission to group and others if absent.

grep POINTS homework_instructions.txt | ls -n

Explanation:

The Linux commands above first create a directory and create and save the homework_instructions.txt file in it. The sudo or su command is used to login as a root user to the system to access administrative privileges.

The user permission is configured to read, write and execute the text file while the group and others are only configured to read the file.
