The Complete Practical Docker Guide - What Are Processes

The video tutorial explains the difference between options and arguments in command-line usage, highlighting how multiple options and arguments can be used in commands. It also covers how to find supported options and mandatory arguments using 'man' or '--help'. The tutorial then introduces processes, explaining that each command initiates a specific process. It distinguishes between short-lived processes, like 'ls' or 'mkdir', and long-running processes, such as bash or C shell. The video aims to provide a foundational understanding of command-line operations and process management.

• Options modify the behavior of a command, while arguments specify the data.

• Options specify the data, while arguments modify the behavior of a command.

• Options are mandatory, while arguments are always optional.

How can you find out which options are supported by a specific command?

• By using the 'man' command or '--help' option.

• By checking the command's website.

• By trial and error.

• By using the 'info' command.

What happens when you enter a command in the terminal?

• It starts a specific process.

• It opens a new terminal window.

• It shuts down the computer.

• It saves the command to a file.

Which of the following is an example of a short-lived process?

• Python interpreter

• Bash shell

• C shell

What is a characteristic of long-running processes?

• They are always visible to the user.

• They require no system resources.

• They stop immediately after execution.

• They continue to run until explicitly stopped.
