Most Valuable Commands – Practical Video Class
A short, high-value sequence worth demonstrating live: setting up a brand-new project folder from nothing, end to end.
- pwd # Confirms exactly which folder you’re in before you do anything else
- mkdir patient-intake-v2 # Creates a new project folder
- cd patient-intake-v2 # Moves into that folder
- touch README.txt # Creates a new, empty file to describe the project
- ls -lh # Lists everything in the folder with sizes and permissions
- cp README.txt README_backup.txt # Makes a safety copy before editing
- grep -n “TODO” README.txt # Finds every TODO note and its line number
- chmod +x setup.sh # Makes a script executable
- ./setup.sh # Runs the script
- history # Reviews every command you just ran, in order
