It says lrzsz is a heavily reworked version of the last public-domain release of Omen Technologies' rzsz package, relicensed as free software under the GNU GPL. The official changelog on the same page records active 0.12.x development from August 1996 through December 1998, focused on portability, syslog support, TCP options, performance, security fixes, Dejagnu tests, and platform support including BeOS and older SCO. ### Adoption history The supplied package-manager facts list lrzsz across Homebrew, Debian, Ubuntu, Fedora, Arch, Nix, MacPorts, Scoop, WinGet, and openSUSE. That packaging persistence reflects how `rz` and `sz` remained useful for terminal-based file transfer, serial links, embedded consoles, BBS-era workflows, and recovery environments. The project page's latest release is 0.12.20 from December 1998, so modern adoption is mostly maintenance packaging of a stable old tool rather than a fast-moving upstream. ### How it is used Users typically invoke `rz` to receive files and `sz` to send files through a terminal or serial session that supports ZMODEM-style transfers. The package also includes prefixed variants such as `lrz`, `lsz`, `lrx`, and `lsx`. No official config file or credential store is documented; transfer behavior is controlled with command-line options and the surrounding terminal or serial connection. ### Why package nerds care lrzsz is package-nerd archaeology that still earns its keep: a compact compatibility package for protocols older than many current distributions, but still handy when the transport is a shell, modem-like terminal, or serial console instead of SSH/SCP. ### Timeline - 1996: Official changelog begins the visible 0.12.x release series. - 1997: Releases add portability work, TCP options, gettext/autoconf updates, and performance improvements. - 1998: Version 0.12.20 becomes the latest official release. - 2026: Supplied package-manager facts list broad packaging across Unix-like and Windows package managers. ### Related projects - lrzsz descends from Omen Technologies' rzsz and implements the XMODEM, YMODEM, and ZMODEM protocol family used by terminal programs and serial-transfer workflows. ### Sources -
