You want to write a script that extracts only the bucket names from aws s3api list-buckets. Which output format should you choose to easily parse the bucket names in a shell script?
AUse <code>--output text</code> for simple tab-separated values.
BUse <code>--output table</code> and extract names from the table.
CUse <code>--output json</code> and parse with a JSON tool.
DUse <code>--output xml</code> for structured parsing.
Step-by-Step Solution
Solution:
Step 1: Consider parsing ease in shell scripts
Shell scripts handle plain text easily, especially tab-separated values.

Use --output text for simple tab-separated values. -> Option A
