履歴

プロジェクトの歴史と使われ方

less is a classic terminal pager: a free, open source program for viewing text one screen at a time, similar to more but with richer navigation and search behavior.

プロジェクトの歴史

The official FAQ says less was written by Mark Nudelman and is maintained by him. The source tree's copyright file dates the code line to 1984, and the README identifies the distribution as part of the GNU project while also documenting a separate Less License option.

The program has stayed under active maintenance for decades. Greenwood Software's release page records many numbered releases from the 2010s and 2020s, while the NEWS file tracks ongoing pager features such as OSC 8 hyperlink handling, command mapping, prompt expansion, mouse support, regex behavior, and platform fixes.

採用の歴史

The official home page describes less as present on most Linux, Unix, and Mac OS systems and on many other operating systems. The FAQ also notes distribution through standard Unix-like system software and GNU archives.

Its adoption is helped by being a drop-in pager for commands and environment variables such as PAGER. Developers use it through man, git, shells, build logs, and package-manager output without always invoking it directly.

使われ方

less opens files or standard input for interactive viewing, with forward and backward movement, searching, marks, filtering, follow mode, and configurable key bindings through lesskey-style configuration.

Package builds usually install the less and lesskey executables plus manual pages. The README recommends downloading numbered release packages from Greenwood Software for ordinary use and cloning the Git repository only for source development.

パッケージ好きにとっての重要性

less is package-nerd bedrock: a tiny command that sits in the path of almost every Unix developer workflow. Its value is partly invisible because many tools delegate paging to it, making the package a system utility dependency rather than an application people consciously launch.

タイムライン

  • 1984: The less source copyright line begins with Mark Nudelman's 1984 copyright.
  • 2011: Greenwood Software recorded less-444 as a general-use release on June 9, 2011.
  • 2021: less-581.2 was released for general use on April 28, 2021.
  • 2026: less-702 was released for general use on May 22, 2026.
