Basic Commands — Knowledge Check
You practiced pwd/ls/cd/mkdir, ~ versus /, cp/mv/rm/cat/less/head, nano and vim save/quit, and a real tree under ~/cyberlium-lab. These ten APPLY scenarios test what you would type under pressure — not which man-page sentence you memorized.
APPLY: You SSH into a lab VM. The prompt looks unfamiliar. Before mkdir or rm, what first two commands prevent the most damage?
APPLY: You want a nested folder ~/cyberlium-lab/module2 even if cyberlium-lab does not exist yet. Which command matches that intent?
APPLY: A teammate cannot see .bashrc in their home listing. They swear the file "is gone." Likely cause?
APPLY: You need the first 10 lines of a large log you own in lab, then maybe page through it. Best pair?
APPLY: You have notes.txt. You want notes-backup.txt AND to keep editing notes.txt. Which is correct?
APPLY: True or False: rm usually moves files into a Trash folder, so rm -rf ~/cyberlium-lab is as reversible as emptying a GUI Recycle Bin later.
APPLY: In nano you finished typing. You want the bytes on disk and the editor closed. Sequence?
APPLY: vim opened a file. You pressed i, typed, then realized it is the wrong file. How do you leave without writing those keystrokes?
APPLY: True or False: cd / and mkdir lab is the recommended way to start the Cyberlium terminal lab because FHS says projects belong next to /etc.
APPLY: Your lab tree should keep a working notes.txt and a backup inside archive/. You already cp'd notes.txt to notes-backup.txt in the same folder. Next command?
