Dojo: Distinct Values in a CSV Column

MediumOne-Liner Dojo10 min
The brief

The file /root/data.csv is comma-separated with no header. In ONE line, pull out the THIRD column, keep only the distinct values, sort them, and write the result to /root/answer.txt (one value per line).

Pick the field by delimiter — don't reach for awk when you only need a column and a dedupe. And remember: sorting and deduping is a single tool, not two.

What you'll do
  • Write the sorted, distinct values of the 3rd CSV column to /root/answer.txt, in one line
