Nope, env just lists environment variables, not all.

I remember a question like this in practice, and I think "set" was the right answer for showing all variables and functions.

I vaguely recall something about "env -a," but I don't think it lists everything. Could it be "set"?

I feel like "env" just shows the environment variables, not all defined ones. Maybe it's "set"?

I think the command to list all variables is "set," but I'm not completely sure. I remember practicing with it.

I've used 'set' before to list variables, so I'm leaning towards that as the answer. But I want to make sure I'm not missing something, so I'll quickly review the other options too.

Okay, let me think this through. I know 'env' lists environment variables, but I'm not sure if that includes user-defined variables and functions. I'll have to double-check the Bash documentation on this.

Hmm, I'm a bit confused on this one. I think it might be C, 'env -a', but I'm not 100% sure.

I'm pretty sure the answer is B. The 'set' command lists all defined variables and functions in Bash.

Whoever came up with D. echo $ENV as an option must be living in a different universe. That's just silly.

The correct answer has to be B. set. I remember learning that in my Bash scripting class.

B. set is the way to go, no doubt about it. It's like the Swiss Army knife of Bash commands.
