What if the path contains spaces? It’s not a hypothetical situation: on macOS, there’s a directory in home called Library, and inside that there are quite a few subdirectories with spaces in their names. (For the purposes of this discussion I’m going to ignore command line options.) That’s a simplified general form of the command line. Then it considers the first unbroken string of characters to be the command, and every subsequent string to be an argument to the command, like this:- $ command argument1 argument2.
When you press return the shell starts parsing the command line and one of the first things it does is to split up the command line at each space. An argument just means a bit of information you want to pass to the command.Ĭommand line arguments are separated from the command, and from each other, by spaces. It has nothing to do with arguing, it’s simply a mathematical term that harks back to the days when most computer programs were written by mathematicians. When you specify a path after a command like this, the path part is called a command line argument. In the macOS Terminal or any Linux/Unix shell, a common command line might look like:- $ ls path The Problem of Spaces On the Command Line
