下载homebrew（如果没有的话）

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"

下载lrzsz

brew install lrzsz

下载iterm2

brew install --cask iterm2

创建iterm2-*.sh

在 /usr/local/bin下，添加两个文件，内容如下

（务必给这两个文件提升权限）
提升权限命令
cd /usr/local/bin
chmod +x iterm2-*

iterm2-recv-zmodem.sh
