C looks tempting, but it won't replace all occurrences.

I thought it was A at first, but B makes more sense.

Elbert 10 months ago

Definitely agree, B is the way to go.

Lezlie 10 months ago

Option B is the correct one!

Jesus 10 months ago

Wait, why does B have a 'g'? Is that really necessary?

Virgie 11 months ago

I thought the command needed to end with a 'g' for it to change all occurrences, but I can't recall if that's in option B or not.

Anglea 11 months ago

I practiced a similar question, and I feel like the correct answer should have the 's' and 'g' together. So, B seems right to me.

Chau 11 months ago

I'm not entirely sure, but I remember something about using slashes in sed commands. Was it option A?

Stephanie 11 months ago

I think the command needs to include a 'g' for global replacement, so maybe it's option B?

Valentin 12 months ago

I think the answer is B. The 's/bob/Bob/g' syntax looks right to me for replacing all instances of 'bob' with 'Bob' in the file 'data'.

I'm a bit unsure about this one. I know sed is powerful for text processing, but I'm not super familiar with the different syntax options. I'll have to review my notes before deciding.

Simona 12 months ago

The key here is the 'g' flag in the sed command, which stands for 'global' and ensures all occurrences are replaced, not just the first one. I'd go with B.

Hmm, I'm a bit confused on this one. I know sed is used for text manipulation, but I'm not totally sure about the specific syntax. I'll have to think this through carefully.

Oliva 1 year ago

I'm pretty sure the answer is B. The 's/bob/Bob/g' syntax in sed is used to replace all occurrences of 'bob' with 'Bob'.
