goes way beyond a plain list. It's like having a Swiss Army Knife of file-viewing options at your fingertips. Here are a few to tickle your fancy:
ls -l
- Unleash the long format. This bad boy gives you a detailed breakdown of your files, including permissions, owner, size, and last modification date. Basically, the full dossier on every file in your directory.ls -a
- See the unseen! This option includes hidden files, those sneaky fellows that start with a dot (.). Perfect for unearthing any secrets lurking in the shadows.ls -h
