What is a typed command — CCA-F Exam Prep

You type "ls" into a terminal. One word.

The computer lists every file in the current folder. No menus, no clicks, no waiting. Two characters. Instant result.

You type "mkdir photos". A folder called "photos" appears. You type "rm old.txt". The file vanishes. No confirmation dialog. No undo.

Each line you type is a command. The computer executes it the instant you press Enter.
