By the end of this lesson you can

Break a real question into a sequence of small filtering steps
Grow a pipeline incrementally, checking the output at each stage
Combine grep, cut, sort, and uniq -c into one analysis
Rank a tally of counts with sort -rn

Before you startEverything so far: grep, cut, sort, uniq, and the pipe |.

First, keep only the high-impact variants. grep is the fastest filter.

Find the HIGH-impact rows in variants.tsv.

Tip

The professional habit: build a pipeline one stage at a time, and run it after each addition to check the output looks right before adding the next |. Debugging a five-stage pipeline you wrote all at once is far harder than growing it step by step.
