E is super useful for redirecting errors!

D is not valid, right? That looks weird.

Wait, is #> even a thing? I’ve never seen that before.

Totally agree, A is definitely one of them!

A and E are valid operators.

I know `>` and `2>&1` are common, but I can't remember if `#>` is valid or just a comment symbol.
CH

I feel like `>>>` is not a valid operator in Bash. I might go with `<` and `2>&1`.

I remember practicing with stream redirection, and I think `2>&1` is valid, but I can't recall if it was an option here.

I think the `<` operator is definitely one of them, but I'm not sure about the second one.

I've got this! The valid stream redirection operators are A, < and E, 2>&1. The others are not standard Bash syntax.
CH
Christiane

Okay, let me see. I know < is for input redirection and > is for output redirection. I think E, 2>&1, is also a valid option, but I'm not sure about the others.
BE

Hmm, this one looks tricky. I'll need to think through the different redirection operators I've learned in Bash to figure this out.
AU

I'm pretty sure the valid stream redirection operators are < and >>, but I'm not 100% sure about the other options.
GE
Geraldine

I'm going with A and E as well. The other options don't look right for stream redirection in Bash.
EL

Haha, Tamala's got a point. I bet someone who's new to Bash would try that and get really confused. 'Why isn't this working?'

D is definitely not a valid option. Who would use triple greater-than signs for redirection? That's just silly.
BO

I agree with Gail. The greater-than symbol (>) is used for output redirection, and the 2>&1 syntax redirects stderr to stdout.
BE
Bernadine

I agree with Gail. The greater-than symbol (>) is used for output redirection, and the 2>&1 syntax redirects stderr to stdout.

A) >
TO

I'm not sure about the other options, but D) >>> doesn't seem like a valid stream redirection operator.
MI
Mitzie

I agree with Tora, E) 2>&1 is definitely valid.
GA
Gail

Hmm, I think A and E are the valid options here. The less-than and greater-than symbols are used for input and output redirection, respectively.
RO
Rose

Yeah, A and E are the valid stream redirection operators in Bash.
LE
Lettie

A and E are the ones that deal with input and output redirection.
VE
Verdell

I think A and E make sense for stream redirection.
KA
Katy

I agree, A and E are the correct options.
TO
Tora

I think E) 2>&1 is valid.
