Tools and first-week setup

The tools a Linux Administration intern uses and how to set up your workspace in week one.

These are the main tools for Linux Administration tasks. You do not need all of them on day one; the Level 1 tasks tell you when to install each one.

Set up your workspace

Create a free GitHub account if you do not have one, with a professional username, and set up your LinkedIn profile: every task is submitted with a LinkedIn post.
Create one repository for the internship, for example linux-administration-internship, with a README that says who you are and what the repo holds.
Keep one folder per task, named with the task number and title, so mentors find your work quickly.
Commit small changes every day with clear messages. Your daily work report uses these commits as proof.
Never commit passwords, API keys or personal data. Put secrets in a .env file and add it to .gitignore.

Task	What to do
Install Linux	Install Ubuntu Server or Rocky Linux in VirtualBox or WSL, and document the steps in a repo named linux-admin-internship.
Filesystem and navigation	Explain the Linux directory tree (/etc, /var, /home, /usr, /tmp) and practise ls, cd, pwd, cp, mv, rm, find and tree.
Files and text	Use cat, less, head, tail, grep, wc, sort, uniq, cut and awk to answer 10 questions about a sample log file.
Users and groups	Create users and groups, set passwords and expiry, add a user to sudo, and remove a user safely.
