zmoden with sz and rz

资源

通常我们 ssh 连上服务器之后要相互之间传送文件的话会需要单独进行 scp 或者 rsync 乃至 ftp，其实不必，用 zmodem 可以更方便的进行。这里以在 MacOS 下为例：

客户端安装脚本

brew install lrzsz

cat 'EOT' > iterm2-recv-zmodem.sh

osascript -e 'tell application "iTerm2" to version' > /dev/null 2>&1 && NAME=iTerm2 || NAME=iTerm
if [[ $NAME = "iTerm" ]]; then
    FILE=`osascript -e 'tell application "iTerm" to activate' -e 'tell application "iTerm" to set thefile to choose folder with prompt "Choose a folder to place received files in"' -e "do shell script (\"echo \"&(quoted form of POSIX path of thefile as Unicode text)&\"\")"`

    FILE=`osascript -e 'tell application "iTerm2" to activate' -e 'tell application "iTerm2" to set thefile to choose folder with prompt "Choose a folder to place received files in"' -e "do shell script (\"echo \"&(quoted form of POSIX path of thefile as Unicode text)&\"\")"`
fi

if [[ $FILE = "" ]]; then
    echo Cancelled.
    # Send ZModem cancel
    echo -e \\x18\\x18\\x18\\x18\\x18
    sleep 1
    echo
    echo \# Cancelled transfer
else
    cd "$FILE"
    /usr/local/bin/rz -E -e -b
    sleep 1
    echo
    echo
    echo \# Sent \-\> $FILE
fi

EOT


chmod +777 iterm2-*-zmodem.sh
mv iterm2-*-zmodem.sh /usr/local/bin/

ITerm 配置

打开配置项 Perference-> Profiles -> Default -> Advanced -> Triggers 添加如下两个

rz

  • Regular expression: rz waiting to receive.**B0100
  • Action: Run Silent Coprocess
  • Parameters: /usr/local/bin/iterm2-send-zmodem.sh

sz

  • Regular expression: **B00000000000000
  • Action: Run Silent Coprocess
  • Parameters: /usr/local/bin/iterm2-recv-zmodem.sh

使用

  • 下载文件的时候直接 sz filename 即可，会弹出文件选择框选择保存位置
  • 上传文件的时候直接 rz，会弹出文件选择框选择本地文件用于上传

注意，tmux 等工具有不同的协议，可能不成功
