I'm doing a job and I have a question with the commands in Linux, first of all I don't understand much about Linux, it's the first time I've used it. The question is, with the command ls -la as I indicate what specific directory I want to look at, for example if I want to look at the desktop directory, how I write it. Is it ls -la / desktop, or is it ls -the desktop and also another question if I write ls, all that is shown on the screen are directories? And if so, could I see them using the ls command, right?
