I agree with B, it's how positional parameters work.

I might be confused, but I thought the script would just print the script name instead of the arguments.

I practiced a similar question, and I believe it outputs the second argument first, so it should be test2 test1.

I'm not entirely sure, but I remember something about the order of arguments being important.

I think the script uses positional parameters, so $1 is the first argument and $2 is the second.

I think the key here is understanding how the shell script is processing the arguments. Since the script is using $2 and $1, the output should be "test2 test1". I'm feeling pretty good about this one.

Hmm, let me think this through. The script is using $2 and $1, so the order of the arguments passed to the script must be important. I'll need to carefully consider the order of the arguments to determine the correct output.

Okay, I've got this. The script is echoing the second argument ($2) followed by the first argument ($1), so the output should be "test2 test1". I'm confident that's the correct answer.

I'm a bit confused here. The script is using $2 and $1, but I'm not sure which one corresponds to the first and second arguments passed to the script. I'll need to double-check the order of the arguments.

Alright, let's think this through. The script is echoing the arguments in reverse order, so B) test2 test1 is the correct output. Easy peasy, lemon squeezy!

This is a no-brainer! The script is just reversing the order of the arguments, so B has to be the right answer. *chuckles* Bash scripts, gotta love 'em!
