It looks like a less-style pager but adds character-set conversion, multilingual regular expressions, Unicode handling, and the `lgrep` mode. ### プロジェクトの歴史 The upstream README in the Debian source records copyright years beginning in 1996 and points to NARITA Tomio's original web documentation. The bundled man page describes lv as a completely original implementation, not code derived from less, grep, or other programs. Release notes show active upstream work through the early 2000s, including Debian-related patches and portability fixes. Version 4.51 was released in January 2004, while later distribution maintenance continued through Debian packaging updates. ### 採用の歴史 lv's adoption is mostly distribution-driven rather than community-site driven. It survives in Debian, Ubuntu, Homebrew, MacPorts, Nix, Fedora-family packaging, and other Unix package collections because it solves a durable terminal problem: viewing and searching multilingual text on older and mixed-encoding systems. The Debian changelog shows ongoing packaging maintenance into 2026, including modern compiler compatibility work, even though the upstream feature history is much older. ### 使われ方 Users run `lv` as a terminal pager and `lgrep` as the grep mode. The man page documents options for input, keyboard, output, pathname, and fallback coding systems, with examples for ISO-8859, Shift-JIS, EUC, Big5, HZ, UTF-7, and UTF-8. The official man page documents a `.lv` configuration file in the user's home directory, an `_lv` file for MSDOS, and the `LV` environment variable. Command-line options are read last, so they override file and environment settings. ### パッケージ好きにとっての重要性 lv is the kind of old terminal utility package that remains valuable precisely because modern stacks still encounter old encodings. For package maintainers it is a small C program with a long tail: patches, portability fixes, and distro maintenance preserve behavior that newer pagers do not always cover. ### タイムライン - 1996: Copyright start year recorded in the upstream README. - 2003: Debian-related patches incorporated in upstream 4.50 release notes. - 2004: lv 4.51 release notes published. - 2026: Debian changelog records a compiler-compatibility non-maintainer upload. ### Related projects - less is the familiar pager interface that lv intentionally resembles. - nkf and tcs are comparable coding-system translation tools mentioned by the lv man page. - grep is the model for the `lgrep` mode. ### ソース - - - - ## セキュリティノート narrow executable package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
