Which of the following is a typical instruction that is found on a Linux command-line script and represents a system shell?

Show Suggested Answer Hide Answer
Suggested Answer: D

The instruction that is found on a Linux command-line script and represents a system shell is #!/bin/bash. This instruction is called a shebang or a hashbang, and it indicates the interpreter that should be used to execute the script. In this case, the interpreter is /bin/bash, which is the path to the bash shell, a common system shell for Linux. A system shell is a program that provides an interface for users to interact with the operating system, either through commands or scripts. A system shell can also perform various tasks, such as file management, process control, variable assignment, etc. The other options are either incorrect or not typical for this purpose. For example, /bin/bash is the path to the bash shell, but it does not indicate the interpreter for the script; #/bin/shell is not a valid shebang or a path to a system shell; >/bin/sh is a redirection operator followed by a path to a system shell, but it does not indicate the interpreter for the script.Reference:CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.2 Given a scenario, create database objects using scripting and programming languages.

Haha, good point. Though I have to say, if I see one more question about file permissions or shell scripting, I might just throw my computer out the window. Can we get some more creative stuff, please?

Come on, you two. Don't be so jaded. This is a certification exam, after all. They need to make sure we know the basics. And honestly, if you can't get this one right, you probably shouldn't be taking the exam in the first place.

Yeah, I agree. The shebang line is a dead giveaway. Though I have to say, I'm a bit tired of these 'spot the obvious answer' type of questions. Where's the challenge?

Hmm, this question seems pretty straightforward. The correct answer is clearly D) #!/bin/bash. That's the typical shebang line you use at the beginning of a Linux shell script to specify the system shell to be used.
