GOOD BYE 🎉

Can you please post an answer key so I can grade my answers? Researching everything is a bit inconvenient lol.

Don't think of the questions as a test of what you know. Use the test to see what is important to know and why. Answer each question by researching it. The more often you go over the same problem or guide the better you will learn it.

Lol I remember when I was in 5th grade.

Some of those questions are retarded. For example;

B) move file1 /user/u101
C) mv /tmp/file1 /user/u101/file2
D) mv /tmp/file1 /user/u101/file1

Which entry below will create and enable a swap partition on /dev/sda2?
A) swap-add /dev/sda2; swap-stat on /dev/sda2
B) makeswap /dev/sda2; addswap /dev/sda2
C) mkswap /dev/sda2; swapon /dev/sda2
D) swap-set /dev/sda2; add-swap /dev/sda2

C) move -r /user/u210/dir1 /user/c340/*
D) move -R /user/u210/dir1/* /user/c340

Question 18 of 40
Which file must be edited to modify the filesystems that will be mounted automatically upon booting?
A) /etc/mount
B) /etc/fstab
C) /etc/filesystems
D) /etc/inittab

Question 15 of 40

A) /etc/default
B) /etc/sysconfig
C) /etc/aboot.conf
D) /etc/inittab

If you, or anyone hasn't noticed already, with all those commands is a pattern.
Make Dir => mkdir
Copy => cp

If you see it and notice it. It becomes rather easy to figure all of those questions out by process of elimination even if you haven't heard of the command. Even file names have the principle. mkfs is a prime example as well. mkfs.ext2, mkfs.fat, mkfs.btrfs and so on.

Who the fuck wrote that ?
The question is stupid in every sense of everything. Everyone that knows what SWAP is would understand why this question is retarded.
