Filter Columns

# 2) Keep only protein-coding rows with high score
filter-columns '$3 == "protein_coding" && $5 >= 0.95' < annotations.tsv

Recommended Workflow

1. Confirm the stream is tab-delimited.
2. Write the predicate as a single quoted awk expression.
3. Run filter-columns in a pipe or with stdin redirection.
4. Spot-check the retained rows before continuing downstream.

Guardrails

• The expression must be quoted as one shell argument, or the shell will split and reinterpret it before awk sees it.
• This wrapper hard-codes tab as the field separator; it is not a CSV-aware filter.
• --help and --version do not provide real documentation in this build.
• The wrapper injects YR and DT awk variables with the current year and date, so avoid accidental name collisions.
