trzsz

trzsz ( trz / tsz ) is a simple file transfer tools, similar to lrzsz ( rz / sz ), and compatible with tmux.

Website: https://trzsz.github.io

Why?

Considering laptop -> hostA -> hostB -> docker -> tmux, using scp or sftp is inconvenience.

In this case, lrzsz ( rz / sz ) is convenient to use, but unfortunately it's not compatible with tmux.

tmux is not going to support rz / sz ( 906, 1439 ), and creating a new tools is much easier than patching tmux.

Installation

On the server

• with Python3

  sudo python3 -m pip install --upgrade trzsz
  

• with Python2

  sudo python2 -m pip install --upgrade trzsz
  

• with Homebrew

  brew update
  brew install trzsz
  

  Can be installed without sudo, just add the installation path ( e.g. ~/.local/bin ) to the PATH environment.

Supported Terminals

• iTerm2 -- check the trzsz-iterm2 installation.

• tabby -- install the tabby-trzsz plugin.

• electerm -- upgrade to 1.19.0 or higher.

• trzsz-go -- supports all terminals that support a local shell.

• trzsz.js -- making webshell in browser and electron terminal supports trzsz.

  Does your terminal supports trzsz as well? Please let me know. I would love to have it on the list.

Trzsz Manual

trz upload files to the remote server

usage: trz [-h] [-v] [-q] [-y] [-b] [-e] [-d] [-B N] [-t N] [path]

Receive file(s), similar to rz and compatible with tmux.

positional arguments:
  path               path to save file(s). (default: current directory)

optional arguments:
  -h, --help         show this help message and exit
  -v, --version      show program's version number and exit
  -q, --quiet        quiet (hide progress bar)
  -y, --overwrite    yes, overwrite existing file(s)
  -b, --binary       binary transfer mode, faster for binary files
  -e, --escape       escape all known control characters
  -d, --directory    transfer directories and files
  -B N, --bufsize N  max buffer chunk size (1K<=N<=1G). (default: 10M)
  -t N, --timeout N  timeout ( N seconds ) for each buffer chunk.
                     N <= 0 means never timeout. (default: 10)

tsz download files from the remote server

usage: tsz [-h] [-v] [-q] [-y] [-b] [-e] [-d] [-B N] [-t N] file [file ...]

Send file(s), similar to sz and compatible with tmux.

positional arguments:
  file               file(s) to be sent

optional arguments:
  -h, --help         show this help message and exit
  -v, --version      show program's version number and exit
  -q, --quiet        quiet (hide progress bar)
  -y, --overwrite    yes, overwrite existing file(s)
  -b, --binary       binary transfer mode, faster for binary files
  -e, --escape       escape all known control characters
  -d, --directory    transfer directories and files
  -B N, --bufsize N  max buffer chunk size (1K<=N<=1G). (default: 10M)
  -t N, --timeout N  timeout ( N seconds ) for each buffer chunk.
                     N <= 0 means never timeout. (default: 10)

Trouble shooting

• If tmux is not running on the remote server, but on the local computer, or on a middle server.

  • Option 1: Use tmux -CC integration with iTerm2, please refer to iTerm2 tmux Integration.
  • Option 2: Install trzsz-go on the local computer, and alias ssh="trzsz ssh" for convenience.

• If an error occurs, and trzsz is hanging up.

  • Press control + c to stop trz or tsz process on the server.
  • For iTerm2 users, press command + option + shift + r to stop iTerm2 Coprocesses.

• If trz -b binary upload fails, and login to server using telnet or docker exec.

  • Try to escape all known control characters, e.g., trz -eb.

• If trz -b binary upload fails, and the server is using Python3 < 3.7.

  • Python3 < 3.7 supports base64 mode, just don't use trz -b, use trz instead.
  • If you want to use trz -b binary upload, upgrade Python3 to 3.7 or higher, or use Python2.

• If trz -b or tsz -b binary transfer fails, and login to server using expect.

  • Try to export LC_CTYPE=C before the expect script. e.g.:

    #!/bin/sh
    export LC_CTYPE=C
    expect -c '
      spawn ssh xxx
      expect "xxx: "
      send "xxx\n"
      interact
    '
