history

Project history and usage

trzsz is a family of terminal file-transfer tools centered on trz for upload and tsz for download. Its official README describes it as similar to lrzsz/rz/sz but compatible with tmux, with support for directories, resume, progress display, Windows servers, native terminal wrappers, web terminals, and drag-and-drop upload.

Project history

The project was created to solve a specific terminal workflow gap: rz/sz-style transfer is convenient through nested SSH, jump hosts, containers, and remote shells, but lrzsz is not compatible with tmux. The README states that tmux was not going to support rz/sz, so trzsz was developed as a tmux-compatible alternative.

Adoption history

The ecosystem expanded from the original Python package into Go, JavaScript, iTerm2, web-terminal, and SSH-client integrations. Official documentation now presents trzsz, tssh, and tsshd together as modern SSH file-transfer and remote-terminal tools, and the README lists supported terminals including tssh, iTerm2, Tabby, electerm, ttyd, trzsz-go, and trzsz.js.

How it is used

The core workflow is server-side installation plus local support. Users run `trz` to receive uploads on the remote side and `tsz` to send downloads, much like rz and sz. The tool is especially useful when scp or sftp become awkward through chains such as laptop to jump host to another host to Docker to tmux.

Why package nerds care

trzsz is significant to package nerds because it revives the classic rz/sz workflow for modern terminal stacks and splits that functionality across multiple packages and languages. Homebrew carries both the original `trzsz` package and the Go-oriented `trzsz-go`, while the wider ecosystem also includes tssh for local support and JavaScript bindings for web terminals.

Timeline

2022: Early release notes show binary mode, interrupt handling, a production release, and directory-transfer support becoming part of the original Python package line.
2023: v1.1.1 added iTerm2 drag-and-drop uploads and Windows/speed optimizations.
2024: v1.1.5 synchronized features from the Go version.
2026: The official site presents trzsz together with tssh and tsshd as a modern SSH file-transfer and remote-terminal toolkit.
