I'm new in the use of the terminal. I have seen in a video that uses ls -al and I don't know what it is. I have found that ls -a is to list all the files even the hidden but I cannot find what does ls -al means. In the same terminal I write man ls -al and it says man: "invalid option -- l" So:
- What does ls -al mean ?
- Where can I this kind of information. Is there any kind of manual or tutorial for very beginners like me ?
