to increase the computer's efficiency
Explanation
The more files it holds, the more "jobs" it has to run, which means that you're computer would be using the same amount of energy running all of them as to less of them. When you close (or delete) some files, it allows the computer to concentrate on only running a smaller amount of files as oppose to a large amount.
hope it helps!
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.
Answer:
This is because the key in relationships['jimmy'] is wrong. The first letter "j" should be uppercase. The key in the given dictionary is "Jimmy" and therefore a lowercase "j" will result in a KeyError exception. The key is case sensitive and therefore a minor mistake in a single letter either in lowercase or uppercase will cause the error. The correct usage of key to address the value should be relationships["Jimmy"].
