tsv-filter

Filter TSV files by column values

TLDR

Filter by column value

$ tsv-filter --eq [1]:[value] [file.tsv]

Greater than

$ tsv-filter --gt [2]:[100] [file.tsv]

String contains

$ tsv-filter --str-in-fld [1]:[pattern] [file.tsv]

Multiple conditions

$ tsv-filter --ge [2]:[10] --le [2]:[100] [file.tsv]

Invert filter

$ tsv-filter --invert --eq [1]:[value] [file.tsv]

SYNOPSIS

tsv-filter [--eq col:val] [--gt col:val] [options] [file]

tsv-filter selects rows from tab-separated value files based on column conditions. It supports both numeric comparisons (equal, greater than, less than) and string operations (contains, exact match), allowing precise filtering of structured data.Multiple conditions can be combined, and they are joined with AND logic by default — all conditions must match for a row to be included. The --invert flag reverses the selection to output non-matching rows instead.Part of the tsv-utils suite, tsv-filter is written in D for high performance on large datasets. Column numbers are 1-based, and the -H flag enables header-aware processing.
