About:
GNU Datamash is a command-line program for basic numerical, textual, and statistical operations. It can perform calculations such as sum, average, max, min, and percentile on tabular data without requiring a database or spreadsheet. The tool is designed for processing text files directly from the command line, making it ideal for data analysis pipelines.

Key Features:

Supports statistical functions like percentile, median, and standard deviation
Performs text processing operations including sorting and collapsing
Handles CSV, TSV, and other delimited data formats
Requires no external dependencies or scripting
Designed for efficient processing of large text files

Use Cases:

Calculating summary statistics from log files or CSV exports
Filtering and transforming data streams in shell scripts
Quickly computing aggregates without loading data into spreadsheets

Alternatives:

awk – More general-purpose text processing, but requires more complex syntax for statistical functions
R – More powerful statistical analysis but heavier and less suited for simple command-line tasks
csvkit – CSV-specific toolkit with similar features but focused on CSV format
