Welcome

The ls command lists what's in a directory — and a few flags turn it from a bare list into a detailed report. In this lab you'll practice the four forms you'll use every day:

1. ls — the plain list
2. ls -l — long format (permissions, owner, size, date)
3. ls -a — reveal hidden files (names starting with .)
4. ls -la — long format and hidden files together
5. ll — a common shortcut for ls -l

The folder on the right is seeded with a couple of normal files and one hidden file (.secret). Watch when it appears and disappears as you change flags.
