To put it bluntly I'm looking for a sort of help option that will show me what I can possibly do with a command, right from the terminal window, kind of like Python's help().A couple of questions:1) Is there a way to see all the ls command options (or whatever they're called (see #3)) in the terminal window, that will show both the options and their descriptions? If so, how? i.e. ls -la : list long format including hidden files2) Is there an common option across every command to invoke that command's options and descriptions (i.e. ls -?)?3) What are the letters or information followed by a dash called? -a, -b, -c etc. Are they options, commands, switches or something else? From my understanding ls is the command and dash something are options, but I've also seen the word switch thrown around and the entire string ls -a referred to as the command.
How to list all LS commands in terminal and their functionalities?
bash;shell;terminal;ls
man ls will give you everything you need to know about the command lsThis works with every commands obviously
