Using Linux Commands
Linux commands are typically issued at the command line, which is a text-based interface. To use a command, you type it at the command prompt and press Enter. The command will then be executed and the output will be displayed on the screen.
For example, to list the contents of the current directory, you would type the command
ls and press Enter. The output of the command will be a list of the files and directories in the current directory.
You can also use command line options to modify the behavior of a command. For example, the
ls command has an option
-l which will list the contents of a directory in a long format. To use this option, you would type the command
ls -l and press Enter.
