Lesson 2 · Listing directories
See what is around you
The ls command shows what a directory contains. Plain ls hides names beginning with a dot. The -a option shows all entries, while -l adds a detailed long format. Short options can be combined after one dash.
Example
ls -l /etcThis lists a different directory in long format. The same command can target your current directory, and adding -a reveals hidden dotfiles.
Try it
Reveal the hidden practice note in your home directory and include long-format details.
