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

Tenesha 11 months ago

Wait, are you sure? I thought it would be A.

Crissy 11 months ago

Definitely B! It prints in reverse order.

Floyd 11 months ago

I’m surprised it doesn’t just print the script name!

Leanora 11 months ago

The output will be test2 test1.

Chantay 11 months ago

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

Glendora 12 months ago

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

Rosann 12 months ago

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

Daisy 1 year ago

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

Oneida 1 year ago

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.

Charlena 1 year ago

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.

Glenna 1 year ago

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.

Casandra 1 year ago

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.

Timmy 1 year ago

Hmm, this looks straightforward. I think the output will be "test2 test1" since the script is echoing the second argument followed by the first argument.

Mozelle 1 year ago

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!

Alease 1 year ago

I'm not sure, but I think the answer is B) test2 test1 as well.

Cory 1 year ago

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!

Bash scripts can be tricky, but this one is pretty straightforward.

Janae 1 year ago

↳ replying to Cory

Yeah, that script is just swapping the arguments around.

I think you're right, B) test2 test1 is the correct output.

Bettyann 1 year ago

I agree with Laurel, because the script will echo the second argument first.

Shaniqua 1 year ago

Let's see, the script is echoing the arguments in reverse order. That means B) test2 test1 is the correct answer. *fingers crossed*

Shanice 1 year ago

I'm feeling confident about this one. The script is clearly just swapping the order of the arguments, so B is the way to go.

User 2: Yeah, that makes sense. The script is just swapping the arguments.

User 1: I think it will output test2 test1.

Coral 1 year ago

Woah, hold up! If the script is echoing the arguments in reverse order, then the answer has to be B. Easy peasy!

Laurel 1 year ago

I think the output will be B) test2 test1.

Glory 1 year ago

Hmm, this looks like a classic shell script argument handling question. I'll go with B) test2 test1.

User4: I agree with User2, it should be B) test2 test1.
