Why Linux Matters
Almost every server you will ever encounter runs Linux. Being comfortable at the command line is not optional — it is the foundation of every other skill in this course.
Essential Commands
cd — change directory ls — list files and folders ls -la — list everything including hidden files pwd — print your current location cat — read a file file — identify what type a file is
Hidden Files
In Linux, files starting with a dot are hidden from normal ls output. Use ls -la to see everything.
Your Target
SSH into the practice server using the terminal on the right.
Once connected, navigate to the /home/student directory and list all files including hidden ones.
The flag is stored in a hidden file in that directory.
Tip
ls -la /home/student
