Sort Uniq Count Rank

sort-uniq-count-rank

Extension of sort-uniq-count. It builds the same intermediate count<TAB>value table, then sorts the result by count descending and by value using the same compact flag bundle.

Quick Start

• Command: ... | sort-uniq-count-rank [bfinrs]
• Local executable: /home/vimalinx/miniforge3/envs/bio/bin/sort-uniq-count-rank
• Primary ranking sort: -k 1,1nr

When To Use This Tool

• Producing a ranked frequency table from repeated text lines
• Finding the most common case-insensitive values in a stream
• Getting directly to “top counts first” output without an extra sort stage
• Reusing the same compact sort-flag conventions as sort-uniq-count

Common Patterns

# Ranked frequency table
printf 'beta\nAlpha\nalpha\nbeta\n' | sort-uniq-count-rank

# Reverse secondary ordering
printf 'a\na\nb\n' | sort-uniq-count-rank r

# Keep only the most frequent rows
cat values.txt | sort-uniq-count-rank | head

Recommended Workflow

1. Feed it one logical item per line.
2. Use it when you want ranked output immediately, otherwise use sort-uniq-count first.
3. Pass only the supported compact sort letters (bfinrs) if you need to alter the secondary sort behavior.
4. Treat the first column as numeric frequency and the second column as the grouped value.

Guardrails

• Like sort-uniq-count, this wrapper is case-insensitive because it always uses uniq -i -c.
• The wrapper sorts internally, so pre-sorted input is unnecessary.
• -h and --version are not metadata paths; they are mangled into downstream sort options. Locally, -h failed with sort: stray character in field spec: invalid field specification '2s'.
• The final ranking sort is sort -t '\t' -k 1,1nr -k "2$flags", so the first column is always descending numeric count and the second-column behavior depends on the derived flag bundle.
• In local testing, printf 'beta\nAlpha\nalpha\nbeta\n' | sort-uniq-count-rank emitted the same two rows as the unranked wrapper because both counts were tied at 2.
