Bash Shell Scripting- Shell Script to start docker service

The video tutorial guides viewers through creating a shell script to start the Docker service. It covers the necessary user privileges, adding conditional logic to check Docker's status, and ensuring the script runs only with appropriate permissions. The tutorial also demonstrates how to enhance the script with messages and handle different user scenarios, including root and sudo privileges.

What is the primary command used to start the Docker service in the script?

• service docker start

• docker start

• systemctl start docker

• docker run

Why is it beneficial to add messages to the script when starting Docker?

• To make the script run faster

• To provide feedback on the script's execution

• To ensure Docker starts automatically

• To reduce the script's size

What exit status indicates that the Docker service is running?

• 0

What is the significance of checking 'id -u' in the script?

• To verify Docker installation

• To check if the user is root

What is the purpose of using 'sudo' in the script?

• To decrease script size

• To allow non-root users with privileges to execute commands
