By default, it displays the names of the files and directories in a simple format. However, you can use various options with the “ls” command to customize the output.

For example, if you want to display the file sizes and permissions along with the names, you can use the “-l” option. The command would look like this:

ls -l

This will give you a detailed listing of the files and directories in the current directory, including their sizes, permissions, and other information.

Another useful command is the “cd” command, which is used to change the current directory. By default, when you open Terminal, you start in your user’s home directory. However, you can navigate to different directories using the “cd” command.

For example, if you want to navigate to a directory called “Documents” that is located in your home directory, you can use the following command:

cd Documents

This will change the current directory to “Documents,” and you can then perform various operations within that directory.

These are just a few examples of the basic commands you can use in the Terminal interface. As you become more comfortable with the Terminal, you’ll discover a wide range of commands and options that can help you accomplish various tasks efficiently.

Basic Terminal Commands

Here are some essential Terminal commands that every Mac user should know:
