brew install lrzsz安装成功后，会在以下路径生成两个可执行文件（具体的路径取决于brew配置，可以用find查找一下）
/usr/local/Cellar/lrzsz/0.12.20/bin/rz
/usr/local/Cellar/lrzsz/0.12.20/bin/sz
建立符号连接
ln -s /usr/local/Cellar/lrzsz/0.12.20/bin/sz /usr/local/bin/sz
ln -s /usr/local/Cellar/lrzsz/0.12.20/bin/rz /usr/local/bin/rz

注意黄色字体，需要修改为实际sz与rz的路径
