history
Miller, whose executable is `mlr`, is John Kerl's command-line data-processing tool for record-oriented formats. Kerl's csv,conf,v7 slides describe the origin as roughly 2015: he wanted a record-aware tool because classic Unix commands such as grep, cut, and sort are line-aware and column-index oriented. The project name and design reflect that Unix-toolkit lineage, but with fields addressed by name rather than by position.
The technical milestone that defines Miller is its key-value record model. Its README describes it as being like awk, sed, cut, join, and sort for CSV, TSV, JSON, JSON Lines, and positionally indexed data; it can add, drop, sort, aggregate, pretty-print, and convert fields while streaming records. The documentation explains that Miller's natural data structure is an insertion-ordered hash map, which lets it handle heterogenous records and format-aware operations such as preserving CSV headers.
Miller's package-manager footprint is broad: the README lists installation through apt, yum, snap, Homebrew, MacPorts, Chocolatey, WinGet, and Scoop, and the av.db record also maps it across APK, Debian, DNF, Nix, Pacman, Ubuntu, and Zypper. It is used as a shell-pipeline tool for data cleaning, ETL preparation, log processing, statistical summaries, format conversion, and database-query post-processing. Its adoption signals include thousands of GitHub stars, many contributors, and community documentation and talks aimed at CSV and command-line data users.
A major implementation milestone was the Go line, represented by Miller 6. The performance documentation notes CSV and record I/O improvements in Miller 6, later allocation and garbage-collection reductions, and a portable single-binary Go implementation with no runtime dependencies. This made Miller easier to distribute as a small CLI while keeping its niche as a data-aware companion to the traditional Unix toolkit, jq, xsv, csvtk, q, Nushell, pandas, and SQL databases.

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
