They usually modify the way the program will run. In our example -l is an option. Without this option, the list will be simply the filenames. When we modify the command with -l , it will display to us the files along with more detailed information. Options are just that: Any command should have some default behavior when called without options.
Most often the order of the options do not matter, but occasionally they may. These are the objects of our sentence. They describe what we want our command to act on. So we are saying we want to list all of our files in our home folder. Some programs may not need arguments. For instance, without arguments, ls will list the files in the directory you are currently in. More on that later.

Again, each program has different arguments, and the order of the arguments typically matter. In the console, you are always working in a directory, or folder, on your computer. We call this your working directory. You can see where you are using pwd short for print working directory.
This command will print out your current location. You can change your directory with cd short for change directory. If you pass it an argument, it will change your to that location, if it exists. This is relative path, because I specified my destination relative to my current directory. Even when you learn what commands you can use, there is still a lot of power in each command or program.
There are often dozens of available options, and depending on your arguments, your command could behave in several different ways. Fortunately, most commands have a manual. To read, use the man command. For instance to learn more about ls , run. There are a ton of different commands you can use, but only a couple dozen will get you pretty effective in the command line.
