I'm not sure, but I think the output might be option E) a b c because the command will echo each token with a space in between.

E) a b c is my guess. It's simple and straightforward, just like the command. Although, maybe the exam writers are trying to trick us. Who knows?

I agree with Linn, the output should be abc because the command will echo each token without any spaces.

D) {a},{b},{c}, looks like it could be the output, but I'm not convinced. This exam is really testing our shell knowledge, isn't it?

Easy peasy, the answer is B) abc. I learned this back in my shell scripting days. Hey, at least it's not a coding question, right?

Hmm, I'm not sure about this one. I'm going to go with C) $token$token$token. Seems like it might be a trick question.

The correct answer is B) abc. The command simply prints out each token in the for loop, which results in the output abc.
