Bash Shell Scripting - "case" Statement

The video tutorial explains the use of case statements in scripting, highlighting their advantages over multiple if statements. It begins with an introduction to case statements, followed by a detailed explanation of if statements using examples. The tutorial then transitions to case statements, demonstrating their implementation with service actions. It also covers handling user input and case sensitivity, concluding with the benefits of using case statements for script clarity and efficiency.

What is the primary purpose of using conditional statements in scripting?

• To execute code based on certain conditions

• To print output to the console

• It displays an error message

• It exits the script

• It prompts for another input

• It does nothing

What is a key advantage of using a case statement over multiple if statements?

• grep

• tr

• awk

What happens if an unrecognized action is entered in the case statement?
