Why the Terminal Beats Clicking

Start Here: Your Beginner Toolkit

These are the must-know commands to get comfy in the terminal. We’ve grouped them by what they do, think of them as your starter pack.

Navigation 101

The terminal’s your map, here’s how to move around:

• pwd: Shows your ‘address’ (e.g., /home/user).
• ls: Lists what’s around you, files and folders (e.g., docs pics).
• cd: Jumps you to a new spot (e.g., cd pics).

$ pwd
/home/user
$ ls
docs  pics  notes.txt
$ cd docs

Create Like a Boss

Build your empire:

• mkdir: Makes a new folder (e.g., mkdir projects).
• touch: Creates an empty file (e.g., touch list.txt).

$ mkdir photos
$ touch photos/shot.jpg

Tidy Your Space

Messy? Clean it:

• rm: Deletes files (e.g., rm list.txt). No take-backs, be sure!
• rmdir: Removes empty folders (e.g., rmdir oldstuff).

$ touch bye.txt
$ rm bye.txt
$ rmdir photos

Read Without Clicking

Check what’s inside:

• cat: Spills a file’s guts (e.g., cat notes.txt).
• more: Shows it page by page, scroll with Space.
• less: Like more, but move up/down (quit with q).

$ cat notes.txt
Buy milk
$ more bigfile.txt
